摘要
以果物桃、杏、葡萄籽的核壳为原料，采用一步热解法制备活性炭，并对所制取的样品进行Ｈ２Ｓ表面改性处理．结果表明，在活性炭的表面引入含Ｓ基团，对水溶液中Ｐｂ２＋的吸附能力明显增强．
Three kinds of activated carbon were prepared from peach,almond stones andgrape seeds by using one-step water steam pyrolysis and their surface properties were measured.The activated carbon made from almond stone was modified with H,S and groups containing element S were introduced into the surface of the activated carbon.This can beproved by the adsorption of lead ion from aqueous solution through iR analysis.
