Contamination of water by toxic heavy metals due to urbanization is a world-wide environmental problem, which changes chemical and biological properties of both surface and ground water. The heavy metals render the water unsuitable for drinking and are also highly toxic to human beings. Removal of heavy metals is therefore essential. Thus, in my present work batch adsorption studies have been used to remove the Cr(VI) from aqueous solution using chitin composite. The data obtained from batch method at optimized conditions have been subjected to Freundlich and Langmuir isotherm studies. The data were suitable for both models indicating favorability.
由于城市化导致的有毒重金属对水的污染是一个全球性的环境问题，它改变了地表水和地下水的化学和生物学特性。这些重金属使水不适合饮用，对人类也有剧毒。因此，去除重金属是必不可少的。因此，在我目前的工作中，使用甲壳素复合材料通过批量吸附研究来去除水溶液中的六价铬。在优化条件下从批量法获得的数据已经进行了弗伦德利希和朗缪尔等温线研究。这些数据适合两种模型，表明其有利性。
