The effect of preparation of biogenic sorbent on zinc sorption
نویسندگان
چکیده
The aim of this study is to prepare biogenic sulphides by using bacteria for the removal of zinc cations from their solutions. The production was realized in a bioreactor under anaerobic conditions at 30 °C. Sorbents were prepared by sulphate-reducing bacteria in different nutrient medium modifications, under two modes of bacteria cultivation. Created precipitates of iron sulphides were removed from the liquid phase of the cultivation medium by filtration, dried and used for the sorption experiments.

A new sorbent has been developed by grafting Hexamethylenetetramine on a mesoporous molecular sieve (SBA-15) by wet impregnation method. This sorbent (Hexamine/SBA-15) has been characterized using N2 physisorption, X-ray diffraction (XRD) at low angles (2θ°) and FT-IR. To investigate the H2S removal capacity of this adsorbent from CH4-containing gas mixtures, the breakthrough tests have been pe...
