Doğan and Alkan, (2003a) used expanded perlite and unexpanded perlite adsorbent to uptake methyl violet. In this analysis, the batch system using perlite powder as an adsorbent was studied as a function of the effects of initial metal concentration (1.5–2.5 mol/L), contact time (0–30 min), and pH (5, 7, 9, and 11).
Bulk handling of expanded perlite and expansion of perlite at the job site are two methods of delivering expanded perlite to the customer without the use of bags. A . d v antages a ) Advantages as compared with bags Buk handng saves the cost of bags. It eliminates the labor of filling the bags at the plant and
