摘要
采用紫外分光光度法研究了活性炭纤维对邻苯二甲酸二甲酯的吸附规律,在优化的条件下,测定波长227 nm时,邻苯二甲酸二甲酯的浓度为2~12 mg/L范围内,与紫外的吸光强度呈现线性关系。实验中研究了吸附时间、盐含量、p H对吸附的影响,并试验了ACF在不同温度下对邻苯二甲酸二甲酯的吸附等温线,结果表明吸附量随初始浓度的增大而增大,随溶液温度的升高而减小,升温不利于吸附的进行。
Absoption behavior of activated carbon fiber to dirnethyl phthalate was studied by UV Spectrophotometry. Under the optimal condition, the detection wavelength was 227 nm, the concentration of the dimetbyl phthalate ranged from 2 mg/L to 12 mg/L, the intensity of the absorptions showed a linear relationship with the concentration of dimethyl pbthalate. The effect of the absorption time, the salt content, pH were investigated, the absorption isotherm of the ACF to dimethyl phthalate at different temperature was also tested. The result indicated the absorption capacity increased with the increasing concentration, and decreased with the increase of the temperature, the rising of the temperature was not conductive to the absorption.
