خلاصه مقاله:
A simple and reproducible method for the rapid extraction and determination of trace amounts of cd(II) ions using Aminopolycarboxylic acid-type cellulose (Chelest Fiber Iry) and Atomic Absorption Spectrometry is presented. Aminopolycarboxylic acid-type cellulose (Chelest Fiber Iry) has been studied for its sorption efficiencies with respect to cd(II) from acidic solution. The influence pH and other properties related to sorption kinetic, isotherm, maximum capacity, stability and the mechanism of the sorption were discussed. Cd(II) was quantitatively retained on the proposed adsorbent in the pH range of 3.0 6 (studied pH range 1.6 6). The maximum sorption capacity was found to be 0.95±0.06 mmol/g adsorbent. The decline in the efficiency of the adsorbent was not observed for repeated adsorption desorption cycles. It was found that the preconcentration factor of 200 can be achieved. The limit of determination was found to be about 1.7μg Cd/2 l. The method was applied to the determination of cd(II) in water samples.
