The cellulose-binding domain (CBD) is the second important and the most wide-spread element of cellulase structure involved in cellulose transformation with a great structural diversity and a range of adsorption behavior toward different types of cellulosic materials. The effect of the CBD from Clostridium cellulovorans on the supramolecular structure of three different sources of cellulose (cotton cellulose, spruce dissolving pulp, and cellulose

The efficiency of Zn (II) removal from aqueous solutions was investigated using Sphagnum moss peat as adsorbent. A 23 full factorial central orthogonal design was carried out in order to achieve the best conditions of the sorption of Zn (II) on peat. The combined effect of initial concentration of Zn (II) in aqueous solution (C0, mg/L), peat dose (G, g/L) and pH was studied and optimized using Response Surface Methodology (RSM). The optimum values

Equilibrium and kinetics of sorption of Zn (II) ions from aqueous solutions of pH 5 on indigene (Romanian) peat moss were investigated in batch system. The experimental equilibrium sorption data at three temperatures were analysed by Freundlich, Langmuir, Tempkin and Dubinin-Radushkevich sorption isotherm models. Results indicate the following order in to fit the isotherm equations: Langmuir > Tempkin > Dubinin-Radushkevich > Freundlich. The equilibrium

In recent years the removal of toxic substances especially heavy metals from water and wastewater by using of non-conventional low-cost sorbents (industrial wastes and some natural material including microorganisms, plant-derived materials, agricultural products and by-products, mineral oxides, clays) has received much attention. In this paper efficiency of Zn (II) removal from aqueous solutions by sorption onto Romanian sphagnum moss peat was studied

An original strategy was set-up in order to develop new azo compounds which incorporate in their structure 4,4'- diaminodiphenylmethane (DADFM) and low molecular weight maltodextrine. The synthesis of the model compounds involved the functionalisation of DADFM with the maltodextrine, the conversion of amino functionalized maltodextrine in a diazonium salt and the coupling of reaction with H and R acids. The compounds were characterized by UV-VIS,
