Abstract

Tetrachloroethylene (TCE) is a chlorinated aliphatic hydrocarbon, used in many industries. Effective and efficient treatment of industrial wastewater, containing TCE, is one of the environmental requirements. The purpose of this study was to determine the role of alkaline environments in TCE removal rate from aqueous solutions, using copper-doped pumice. This experimental study was performed, using granulated pumice stones with a mesh 4 (8.4 mm) in alkaline conditions; the samples were coated with copper. Copper-doped pumice was prepared as a bed at doses of 1, 2, and 3 g/L; the study was performed at pH ranges of 3, 7, and 11. Based on the results, copper-doped pumice showed good efficacy in TCE removal; in addition, its performance increased in alkaline conditions. Therefore, use of this stone for the treatment of wastewater, containing TCE, is effective due to its availability and low cost. Besides, it can be considered a good option, given its high efficiency in the absorption process.

掺铜浮石对水溶液中四氯乙烯的去除率:pH影响的评价

四氯乙烯(TCE)是一种氯化脂肪族烃，在许多工业中都有应用。有效和高效地处理含TCE的工业废水是环境要求之一。本研究的目的是利用掺铜浮石确定碱性环境对水溶液中TCE去除率的影响。本实验研究是在碱性条件下使用粒径为4 (8.4 mm)的浮石颗粒进行的;样品被镀上了一层铜。在1、2和3 g/L的剂量下制备掺杂铜的浮石作为床层;研究在3、7和11的pH范围内进行。结果表明，掺铜浮石对TCE有较好的去除效果;此外，在碱性条件下，其性能有所提高。因此，使用这种石头来处理含有TCE的废水，由于其可用性和低成本，是有效的。此外，考虑到它在吸收过程中的高效率，它可以被认为是一个很好的选择。
