Abstract

The aim of this study was to investigate the influence of operating parameters on lead removal from wastewater by phosphogypsum. Batch adsorption studies were carried out to examine the effect of these parameters on lead removal from wastewater. The operating parameters investigated were adsorbent dosage, contact time, pH and initial lead concentration. Adsorption isotherms were modelled with the help of both Langmuir and Freundlich formulae. The kinetics of the adsorption process which is important in the design of waste treatment systems, was also studied.

摘要

本研究的目的是调查操作参数对磷石膏去除废水中铅的影响。进行了批量吸附研究，以检验这些参数对废水中铅去除效果的影响。所研究的操作参数包括吸附剂用量、接触时间、pH值和初始铅浓度。吸附等温线借助朗缪尔和弗伦德里希公式进行建模。还研究了吸附过程的动力学，这在废物处理系统设计中很重要。
