| Summary: | Removal of silver from wastewater was investigated using continuous cross flow microfiltration (MF) technique hollow fiber membranes with a pore size 0.2μm, with sorbent coated material Al2O3/SDSH2Dz particle size (8 μm). The coating investigated was dithizone (Diphenylthiocarbazone) in 0.005M ammonia solution. In the filtration of silver ion solutions, the effects of the permeate flow rate and cross flow velocity on the absorption of silver ion solutions, and since the pore size of membrane (=0.2 μm) is smaller then that of the (Al2O3), no need to consider the variation of (Al2O3).rejection as it can be considered to be 100%. The amount of silver absorbed into sorbent material Al2O3/SDSH2Dz was (25.35, 39.68 ppm) for the cross flown velocity of 5, 2.5 L/hr respectively, and were the results as function of permeate flow was (25.35, 39.68 ppm) for the velocity of 5, 2.5 L/hr respectively.
