摘要/Abstract

摘要：

将硫酸钙作为添加剂与污泥共热解制备硫酸钙/污泥基生物炭（SBC），并使用BET、SEM、FTIR和XRD表征，研究了其对Pb²⁺的吸附去除特性。结果表明，硫酸钙已负载在生物炭表面并对去除Pb²⁺有促进作用。当温度为25℃，初始pH为5，SBC投加量为0.4 g/L，吸附时间为240 min时，Pb²⁺去除率可达99.69%。Langmuir等温吸附模型能更好地描述SBC对Pb²⁺的吸附过程，最大吸附量为280.899 mg/g；SBC对Pb²⁺的吸附更符合准二级动力学模型，该吸附过程可能以化学吸附为主；热力学分析表明SBC对Pb²⁺的吸附是自发的吸热过程，升温有利于吸附。

Abstract:

Calcium sulfate/sludge based biochar(SBC) was prepared by co-pyrolysis of calcium sulfate and sludge, and characterized by BET, SEM, FTIR and XRD. Its adsorption and removal characteristics of Pb²⁺ were studied. The results showed that calcium sulfate was loaded on the surface of biochar and promoted the removal of Pb²⁺. With the condition of temperature 25℃, the initial pH 5, the dosage of SBC 0.4 g/L and the adsorption time 240 min, the removal ratio of Pb²⁺ could reach 99.69%. Langmuir model can better describe the adsorption process of SBC to Pb²⁺, and the maximum adsorption capacity is 280.899 mg/g. Moreover, the adsorption process of Pb²⁺ is more in line with the quasi second-order kinetic model, which indicates that the adsorption process may be dominated by chemical adsorption. The thermodynamic analysis shows that the adsorption of Pb²⁺ by SBC is a spontaneous endothermic process, and the temperature rise is favorable for adsorption.

Key words: sludge based biochar, lead, adsorption, kinetics, thermodynamics
