本文研究了粉煤灰对模拟酸性矿井水中Cd²⁺的吸附。实验选取Cd²⁺的初始浓度从0.0001mol/L到0.01mol/L, 结果表明粉煤灰对Cd²⁺的吸附符合Freundlich型吸附等温式, 等温吸附方程为Γ=4.432×10^-8C^6.4317 mg/g。吸附反应符合一级反应动力学特征, 可表示为C=C₀e^-kt。在不同温度下得到速率常数方程k=68.9e^-Ea/T, 表观活化能Ea=28.95kJ/mol, 指前因子A=68.9min^-1。俄语翻译

Abstract: This article studies the Cd²⁺adsorption of fly ash in mimic acid mine water. The experiment selected for Cd²⁺ initiative concentration from 0.0001mol/L to 0.01mol/L shows the adsorption of Cd2 with fly ash is consistent with absorption isotherm of Freundlich type with Adsorption isotherm equation,Γ=4.432×10^-8C^6.4317 mg/g and such adsorption reaction conforms to first order reaction kinetics, expressed with C=C₀e^-kt rate constant equation k=68.9e^-Ea/T, apparent activation energy Ea=28.95kJ/mol, pre-exponential factor A=68.9min^-may be obtained in different temperature ¹

目前, 我国煤炭行业矿井水的年排放量约16 亿t , 大量的矿井水未经处理直接排放, 不仅对矿区周围环境造成严重污染, 而且是一种巨大的水资源浪费^[1] 。调查表明酸性矿井水中含有镉等多种重金属离子。现代医学证明镉对人体组织及血液系统均产生毒性作用, 因此对矿井水中镉的去除的研究具有重要意义翻译公司。

At present, annual mine water discharging is about 1.6billion tons in coal mine industry in China. The direct discharging without treatment not only brings serious pollution to environment but create great water waste. The investigation shows that a few heavy metals ion such as cadmium exists in acid mine water. The modern medicine study shows that cadmium will give toxicity to human, especially to blood system. The study on the removal of cadmium from water is significant.
