邻苯二甲酸二甲酯%活性炭纤维%吸附
鄰苯二甲痠二甲酯%活性炭纖維%吸附
린분이갑산이갑지%활성탄섬유%흡부
dimethyl phthalate%activated carbon fiber%absorption
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、 pH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。
採用紫外分光光度法研究瞭活性炭纖維對鄰苯二甲痠二甲酯的吸附規律，在優化的條件下，測定波長227 nm時，鄰苯二甲痠二甲酯的濃度為2~12 mg/L範圍內，與紫外的吸光彊度呈現線性關繫。實驗中研究瞭吸附時間、鹽含量、 pH對吸附的影響，併試驗瞭ACF在不同溫度下對鄰苯二甲痠二甲酯的吸附等溫線，結果錶明吸附量隨初始濃度的增大而增大，隨溶液溫度的升高而減小，升溫不利于吸附的進行。

Absoption behavior of activated carbon fiber to dimethyl phthalate was studied by UV Spectrophotometry. Under the optimal condition, the detection wavelength was 227 nm, the concentration of the dimethyl phthalate ranged from 2 mg/L to 12 mg/L, the intensity of the absorptions showed a linear relationship with the concentration of dimethyl phthalate. 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.
