چکیده
|
In this study, the sorption of as(v) by natural modified zeolites (clinoptilolite) was investigated through the batch process in aqueous solutions# for this purpose the effect of various factors including ph, temperature, initial concentration of pollutants (arsenic) and adsorbent dosage affecting adsorption mechanism of zeolite in a time frame of 48 hours were accurately measured#on the basis of batch experiments, the adsorption capacity of natural zeolite was found to be 1#5 μg/g and the amount of adsorption of modified zeolite by lacl3#7h2o enhanced to 2770#4 μg/g#furthermore, the adsorption of arsenic by means of natural modified zeolite depicted that the maximum amount of adsorption tool place in the range of 4 < ph < 8 #
