摘要

研究了当地廉价的天然吸附剂椰子壳对Cu（II）的吸附特性。本研究的吸附过程是通过固定床柱进行的，以找出突破性的特征。研究了操作变量的变化，pH 6，影响Cu（II）浓度（10-30 mg·L–1），床高（5-15 cm），流速（10-30 ml·min–1）。已经测试了各种动力学模型的适用性。根据Thomas模型，最大吸附容量qe为30.09 mg·g–1，在20 ml/min、流速、30 mg·L–1金属溶液和15 cm床高下获得。托马斯模型的相关系数在0.8260到0.9839之间。此外，根据Yoon Nelson和Yan等人模型的统计参数，证明实验数据适用于该模型。还成功地对实验数据进行了统计和遗传算法建模。

COLUMN STUDY FOR THE CU(II) REMOVAL BY THE COCONUT SHELL FROM AQUEOUS SOLUTION – MLR AND GA MODELING

Adsorption characteristics of locally available inexpensive natural adsorbent coconut shells were studied for Cu(II) removal. The present study adsorption process was carried through a fixed bed column to find out the breakthrough characteristics. The variation of operating variables is investigated, pH 6, influence Cu(II) concentration (10–30 mg·L–1), bed height (5–15 cm), the flow rate (10–30 ml·min–1). The suitability of various kinetic models has been tested. Maximum adsorption capacity, qe according to Thomas model, was 30.09 mg·g–1obtained at 20 ml/min, flow rate, 30 mg·L–1 metal solution, and 15 cm bed height. The correlation coefficient of the Thomas model ranges from 0.8260 to 0.9839. Besides this, according to the statistical parameters of the Yoon-Nelson and Yan et al. models, proving that the experimental data are suitable for this model. The statistical and GA modeling of the experimental data has also been performed successfully.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
