Abstract Pyrolysis was applied for post treatment of two crop residues contaminated by heavy metal cadmium (Cd) after biosorption, with phosphorus additives used for enhancing the recovery and stability of Cd in the char. The results indicate that phosphoric acid (PA) can increase the Cd recovery in char to a level of > 90% at the PA dosage of 71–143 mg/g biomass, when the plant residues were pyrolyzed at 350 °C. The pyrolysis with phosphorus additives reduced the bioavailable Cd to

磷添加剂对污染生物质热解炭中重金属镉的固定作用

摘要 采用热解法对两种受重金属镉（Cd）污染的作物残留物进行生物吸附后处理，并添加磷添加剂以提高炭中镉的回收率和稳定性。结果表明，当植物残留物在 350 °C 下热解时，磷酸 (PA) 可以将焦炭中的 Cd 回收率提高到 > 90%，PA 剂量为 71–143 mg/g 生物质。含磷添加剂的热解将生物可利用的 Cd 降低到
