Abstract
This study was aimed to find a new, cheap available adsorbent for the removing of Pb from water, using shells of Mollusca (Pomacea canaliculanta). In order to estimate the efficiency of the new adsorbent in removing the heavy metal, batch experiments were achived. At the beginning the best contact time was determined which is equal to 2 hours. then the effect of the initial lead concentrations was studied which demonstrated a direct correlation between the removal efficiency of the adsorbent and the Pb concentration up to 93.98 percent at lead concentration of 60 ppm. After that the effect of adsorbent weight on the removal of the metal was examined which show that 0.75 gm give the best removal efficiency up to 79.08 of the lead initial concentration, as well as the pH value effect on the lead adsorption was evaluated. The results show that the proposed adsorbent has a very good ability for removing the lead, through the whole experiments.
期刊介绍：
IRAQI JOURNAL OF AGRICULTURAL SCIENCES (IJAS)is the first agric. scientific and refereed journal established in Iraq. The first volume was published in 1966. IJAS is registered in the number 137 in 1988 of the Baghdad National Library. Years ago, it was published with one issue a year. For the time being, it is published bimonthly (6 issues for a volume). IJAS Deal with: Field Crops. Plant Breeding. Agricultural Economics. Agricultural Extension. Agricultural Mechanization. Basic sciences. Hort. Sciences. Animal Husbandry. Food Technology, Plant Pathology. Plant Entomology. Poultry Sciences. Soil Sciences. Water Resources. Veterinary. Biology.
