摘要
研究以废弃的香芋皮作为新型生物吸附剂,研究了粒径、投加量、p H、温度、时间等因素对吸附性能的影响。研究结果表明:在香芋皮粒径为180目,投加量为1.00 g,p H 5.0,30℃下吸附240 min的条件下,香芋皮粉末对Cu(Ⅱ)的吸附率达到96.10%,吸附量为4.81 mg/g。吸附热力学反应符合Langmuir吸附等温方程,吸附动力学反应符合准二级动力学方程。
It was based on abandoned taro peel as a new biological adsorbent. Effects of parameters including size, dosage, pH, temperature and time on the adsorption properties were investigated. The results showed that the adsorption properties could reach a maximum under size of 180 mesh, dosage of 1.00 g, pH of 5.0, temperature of 30 ℃ and time of 240 min. The adsorption rote was 96.10%. Adsorption capacity was 4.81 mg/g. The adsorption reaction was consistent with a Cu （ Ⅱ ） order kinetic equation, and the adsorption isotherm could be described well with the Langmuir equation.
