Batch Adsorption Studies of Cadmium in Wastewater on Bentonites

This study describes the batch adsorption process for the removal of cadmium from wastewater using natural bentonites taken from various areas of Pakistan. Bentonite contains montmorillonite, which has the quality to adsorb inorganic and organic materials. Relying upon atomic absorption spectroscopy, the quantities of toxic metals before and after the treatment of their standard solutions with different samples of bentonite were determined at room temperature and -200 mesh particle size. The percentage adsorption for cadmium on bentonite samples was determined
