这一荟萃分析评估了报告废水中重金属和染料的热力学参数的吸附研究。这些吸附剂是从农业废物、工业废物、无机颗粒或一些天然产品中提取的。讨论了吸附机理、热力学关系式的推导以及在这种评价中可能存在的缺陷。这一分析表明，由所考察的标准热焓和标准熵变化得出的结论具有很强的争议性。造成这一缺陷的原因可能是所测试的吸附剂的物理结构较差，因此孔隙传输控制了溶质流动，使表面反应过程接近平衡。(C)2013爱思唯尔有限公司。保留所有权利。
This meta-analysis evaluates adsorption studies that report thermodynamic parameters for heavy metals and dyes from wastewaters. The adsorbents were derived from agricultural waste, industrial wastes, inorganic particulates, or some natural products. The adsorption mechanisms, derivation of thermodynamic relationships, and possible flaws made in such evaluation are discussed. This analysis shows that conclusions from the examined standard enthalpy and entropy changes are highly contestable. The reason for this flaw may be the poor physical structure of adsorbents tested, such that pore transport controlled the solute flux, leaving a surface reaction process near equilibrium.
