摘要: Abstract Porous carbon has been prepared from waste antibiotic material by a chemical activation method using K2CO3 as an activating reagent. Carbon was studied systematically the adsorption of nitrogen and iodine. It found that process parameters such temperature time are crucial for preparing high-quality activated carbon. The proper choice preparation conditions allows to produce microporous with micropore volume up 0.492 cm3/g BET surface area 1260 m2/g. Adsorption mercury(II) aqueous solution on investigated under varying agitation time, metal ion concentration pH. capacity is 129 mg/g.
