用玉米芯制备生物碳，并通过批处理平衡试验，分析了生物碳对 Cd2＋的吸附热力学、吸附动力学以及影响其吸附的因素，结果表明：生物碳的产率随着热解温度升高逐渐降低且其颜色呈现红棕色－浅黑色－黑色－深黑色变化，其对 Cd2＋的吸附在12 h 达到平衡，吸附量随着 pH 的升高而增加，该吸附反应在常温下是自发进行的，反应更符合 Langmuir 模型，动力学更符合准二级动力学模型。

Preparation of bio-char with corn bco ,and through the batch balance test,analysis of the bio-char thermodynamics,kinetics of Cd2 + and factors that affect the adsorption,the results showed that the yield of the bio-carbon with pyrolysis temperature decreases gradually and the colors red brown-shallow black-black-deep black change,its adsorption of Cd2 +1 2 hours in balance,the adsorption quantity increases with the increase of pH,the adsorption reaction is spontaneous reaction,reaction conforms to the Langmuir model,dynamic more accordant with the secondary dynamic model.
