Cadmium(II) adsorption was investigated on different adsorbents, namely Lycopersicon esculentum peel (LEP), Lycopersicon esculentum peel activated carbon (LEP-AC), Brassica botrytis leaves (BBL) and Brassica botrytis leaves activated carbon (BBL-AC). Batch experiments were performed to study the effects of pH, temperature, initial metal ion concentration, contact time and adsorbent dosage. The study concluded that the incorporation of activated carbon to the parental adsorbents leads to accelerate the rate of adsorption. The process was exothermic and due to the exothermic nature, the percent adsorption was decreased by increasing temperature. The experimental data were evaluated by Lagergren and Ho’s kinetic models by taking into account the adsorption of Cd by different adsorbents.

研究了镉（II）在不同的吸附剂上的吸附，分别为番茄，番茄活性炭（LEP-AC），芸苔属植物叶片（BBL）和芸苔属植物留下活性炭（BBL-AC）。进行批处理实验以研究pH，温度，初始金属离子浓度，接触时间和吸附剂用量的影响。研究得出的结论是，活性炭与母体吸附剂的结合会加快吸附速度。该过程是放热的，由于放热的性质，吸附百分率随温度升高而降低。通过考虑不同吸附剂对Cd的吸附，通过Lagergren和Ho的动力学模型评估了实验数据。
