【摘要】 通过活性炭对不同分子结构的有机物--阳离子嫩黄和苯酚、不同水体环境中苯酚的吸附,以及对水源水中挥发性有机物和可提取有机物的吸附规律研究结果表明,活性炭对水体中有机物的吸附量不仅与有机物的分子结构有关,而且与水体中有机物种类的多寡有关,水体中的各种有机物在活性炭上存在竞争吸附,对于挥发性有机物,随分子量的增大,其在活性炭上的吸附量越大;而对可提取有机物,随分子量的增大,其吸附量反而减小。更多还原

【Abstract】 The adsorption of activated carbon to cation light yellow and phynol-the organics with different molecular structure,the phynol in different water environmenlts, and the adsorbing law of activated carbon for volatile organic compounds and extractable organic compound were studied. The results showed that the adsorption quantity of activated carbon to the organic compounds in water was related not only to the molecular structure of organic compounds, but to the number of categories of organic compounds in water; various organic compounds in water have competitive adsorption on activated carbon; the adsorption quantity of volatile organic compounds on activated carbon increased with increases in molecular weight, while the extractable organic compound, decreased with increases in molecular weight rather than increasing.更多还原
