摘　　要：研究了氯苯和腐殖酸在活性炭上的竞争吸附。采用1stOpt和MATLAB数据拟合软件解决了氯苯和腐殖酸在活性炭上竞争吸附的多元非线性模型拟合问题,拟合得到的参数方程可以模拟氯苯和腐殖酸在活性炭上的竞争吸附行为。按照拟合方程绘制的三维图形表明,腐殖酸浓度越高,氯苯浓度越低,氯苯被活性炭吸附时受腐殖酸的影响越大,其影响程度可由方程计算得出,可为活性炭滤柱的设计提供基础参数。The competitive adsorption of ehlorobenzene and humic acid on activated carbon was studied. Multi-variables nonlinear model fitting of the competitive adsorption of chlorobenzene and humic acid on activated carbon was made by 1 stOpt and MATLAB fitting software, and the equation from them could simulate the behavior of competitive adsorption. The three-dimensional graph drawn by the fitting equation showed that the higher the concentration of humie acid was, the lower the concentration of ehlorobenzene was, the more influence of humic acid on ehlorobenzene adsorbed by activated carbon was, its influence degree could be calculated by the equations, and could provide basic parameters for the design of activated carbon filter columns.
