摘要: The effects of raw material treatment and concentration phosphoric acid on the characteristics activated carbon were investigated. Adsorptions Cu, Pb, Cr Cd in carried out to evaluate adsorptive capacity selected carbons. It was found that treated reduces inorganic element increases Brunet Elmer Teller (BET) surface area carbon. optimum BET achieved with following conditions; 30% concentration, material, activation temperature 500oC holding time 2 hours. average pore diameter be 1058 m2g-1 20.64nm, respectively. size distribution by scanning electron microscopy (SEM) also confirmed these conditions. Thermal stability samples investigated using thermal gravimetric analyzer (TGA). maximum observed up 600oC. Adsorption studies for impregnated H3PO4 application filter system confirm adsorbing In this study, it 100% adsorbed followed Pb (99.8 %), (99.5 %) Cu (25 %).
