Abstract:

We used salt addition, mass and potentiometric fast titration to determine point of zero charge of chitosan, (chitosan + cellulose and chitosan + Algenite) biosorbents in presence of textile waste water. Comprehensive potentiometric experiments were conducted to find the surface acidity constants and the concentration of surface charged groups on the biosorbents. The PZC of chitosan based novel biosorbents is comparable in magnitude to the one obtained by salt addition and mass titration techniques at 303 K. However the slight differences in the PZC values obtained by different methods diminish at higher temperatures. We observed the fair agreement between experimental and calculated values of PZC. The influence of ionic strength and temperature on the acidity constant of biosorbents were investigated. The intrinsic acidity constants (pK1 and pK2) were found to decrease with increase in temperature, which shows endothermic nature of both biosorbent surfaces deprotonation reactions. The PZC and the concentration of surface groups were increased whre as concentration of pure biosorbent material decreased with decrease in temperature of medium. The changes in entropy (∆S) and enthalpy (∆H) connected with the surfaces deprotonation of the biosorbent composite materials/ electrolyte interface were measured. The loss in entropy indicated that potential determining ions were less hydrated at the interfacial regions. Themodynamic parameters showed that the positive values of enthalpy were the driving force for the depronation of the both biosorbents.

Title: Reutilization of avocado seed as beneficial product in leather processing after some extraction
Biography:

Menbere Kinfe Habtie has completed my BSC Degree at the age of 22 years from 2001 to 2006 I have an experience in company of leather sector as a consultant in environemental issue for this I have taken a training in Germany about environmental standards and what thier expriance looks like in protacting environenment in adition my job is consulting the company to produce quality product by minimazing ther waste

Abstract:

This study focuses on the reutilization of avocado seed as beneficial product in leather processing after some extraction. Avocado seed are one of the most important by-products from fruit juice processing industry. Avocado seed have two part of fraction i.e. tannin and oil components. The oil was extracted from avocado seed obtained by dichloromethane (DCM), n-haxane (HE) and petroleum ether (PE) solvent and the tannin extraction of avocado seed was obtained by water base and hexane. The extracted tannin and oil from avocado seed was used for preparation of lubricant retanning agents and used in retannage of upper leathers.
The oil and the extracted tannin fractions were characterized and then used in the development of the product. Various parameters, such as time, temperature and solvent (concentration and amount) of tannin liquor have been optimized. The optimized product was used in the retanning of upper leathers.
The results of the study showed that various parameters contributed to the extraction optimization of avocado seed oil as the n –hexane gave higher oil yields 1.59% as compared to other solvent.
According to the physicochemical analysis of the oil extract has been shown 3.63%, 7.73 mg, 51.8 mg iodine/g , 207 .3 mg KOH/ g and 214.5 mg KOH/ g of Free fatty Acid ( FFA), acid value ( AV), Iodine value (IV), Ester value (EV) and Saponification value (SV).
Literally there is an indication of the phenolic group are existed on the seed. To proof this we tried in different factor of solvent, time and temperature. The result of this is checked with FTIR analysis; from the result for 8hr at 1000c is showed better resolution then other factors of extraction. And also the fine solid power of hexane extracted has shown the maximum amount of phenolic groups.
The physical properties of sheep shoe upper leather were on par with that of the control leathers. The color intensity of the experimental leathers is better than the control leathers.
Finaly this reaserch had been applied the waste recycling from municpal samll processing industries to industrial level of solid dischargi

Abstract:

This study carried out on the modeling, mathematical (by reaction mechanisms) and experimental (empirical modeling) of an electrochemical reactor of porous bed for convertion of hydrogen sulphide into sulfates and thiosulphates, products used in various industrial processes. The applied mathematical modeling of electrochemical phenomena theory consists of a set of partial differential equations that essentially describes the transport of the species in solution, the electric potential distribution and the charge transfer kinetics at the electrode / electrolyte interface. The solution of the equations, through appropriate numerical methods (finite element method), provides theoretical relations between the quantities of interest (current, potential, concentration, among others), which allows the quantitative analysis of the experiments. The experimental modeling cover the optimization applied to the problems of parameter estimation and discrimination of the empirical model. The study is composed of a theoretical stage, referred to above and an experimental stage. In the experimental stage it was carried out tests in a bench electrochemical reactor, with perpendicular configuration and porous bed composed of reticulated vitreous carbon. As a result, sulfide, sulphate and thiosulphate concentration profiles were obtained, and current and applied potential profiles. Thus, the performance of the electrochemical reactor for different hydrodynamic conditions and applied electric potential was evaluated.

Abstract:

Luminescent organic polymers are important materials for organic light-emitting diodes (OLEDs) due to their tunable emission properties through molecular design and their inherent flexible nature and readiness in fabrication.  Especially, circularly-polarized light (CPL) emitting polymers are drawing attention because CPL can be applied for energy-saving LCD backlights and 3D OLED displays.  Toward this end, several chiral OELD polymers and low-molecular-weight compounds have been synthesized; however, majority of the existing polymers have linear conjugated structures.  For such polymers, there are two aspects that need to be improved, i.e., (1) their emission tends to be of lower energy (longer wavelength) due to the presence of the main-chain conjugation, and (2) inter-chain interactions including excimer formation often result in low emission efficiency.  We herein present the design and synthesis of a vinyl polymer having a -stacked, helical conformation that exhibits higher-energy CPL emission (poly(BBPDBF)) [1-5] and a hyperbranched polymer that emits green CPL with high anisotropy in addition to a main-chain conjugated polymer [6].  In addition, as a novel, facile method of creating optically active, CPL-emitting polymers, we introduce the CPL-irradiation method.  Several polymers including poly(DOF) have been made single-handed helical without using any optically active chemicals to induce chiral structure to polymer [7,8]. Optically active polymers prepared using CPL emitted efficient CPL on photo excitation.
