The aim of this paper is to model and optimize the conditions of obtaining the activated carbon prepared from the date cores, and the elimination of phenol by adsorption. Several activation chemical agents were tested for the preparation of the activated carbon. Best results is obtained with the pho

This study first illustrates the IEMB potential for the simultaneous removal of nitrate, perchlorate and bromate from drinking water. The removal of each of these pollutants to concentrations below the recommended levels for drinking water was successfully achieved. The initial development of the IE

Boron is biologically an essential nutrient for many plants but high boron concentrations in irrigation water cause toxic effects whereas low abundances require boron addition to maximize crop yields. High boron levels in drinking water can be also toxic to humans. There is no easy method for the re

In this study removal of boron from aqueous solutions by adsorption was investigated and experimental design was applied. Cerium oxide was used as adsorbent. In the first part of study 3 parameters effect performance and two levels of these parameters were investigated. Parameters that were chosen t

A water-soluble copolymeric membrane material containing tertiary amine and carboxyl groups for CO2 facilitated transport has been synthesized by radical polymerization of DMAEMA(2-N,N-dimethyl aminoethyl methacrylate)-AA(acrylic acid). The composition the copolymer was determined by elemental analy

In recent years, the increasing level of underground water shows a high iron and manganese concentrations, thus, the technology of water treatment requires application of processes for Fe and Mn removal. Within a literature, many treatment processes have been proposed for manganese removal from drin

The nature of the metal (Mg and/or Fe) salts, used as precursors during the synthesis process of layered double hydroxides, is used as a controlled variable synthesis parameter to obtain iron-containing anionic clay matrices with specific properties. The XRD and N2 adsorption at 77 K analyses indica

Removal of nitrate anion from aqueous solution stays one of the principal goals of much study concerning water treatment. Besides biological and membrane separation treatment, Anion exchange resin technique has been widely investigated and the most result was leading to an efficient elimination. In

The main purpose of this work is the study of the viability of a polyelectrolyte enhanced ultrafiltration (PEUF) process for the chromate recovery using poly(diallyldimethylammonium chloride) (PDADMAC) as water-soluble polymer. First of all, the interaction between PDADMAC and chromate ions was stud

There has been a growing interest in the use of inorganic membrane for several industrial and laboratory applications. This is because they offer many advantages over organic counterparts in separation processes. These include resistance to compaction under high pressure, chemical stability at high
