以竹炭为载体,钛酸四正丁酯为钛源,通过溶胶-凝胶法制备TiO2/竹炭复合材料,研究材料对罗丹明B溶液的暗室吸附规律和光降解性能。实验结果表明：材料对罗丹明B的吸附属于物理吸附,能较好地符合Freundlich吸附等温模型;材料对罗丹明B的降解率高,且随溶液pH的变化而有明显改变。此光催化反应可用一级反应动力学方程进行描述。

TiO2/bamboo charcoal composite was prepared by sol-gel technique with tetra-n-butyl tinanate as the titanium source,and bamboo charcoal as the support.The adsorption behavior and the photocatalytic degradation processes of Rhodamine B were studied.The results indicated that the adsorption of Rhodamine B on the composites was physical adsorption and adsorption law of Rhodamine B on the composites fits in well with Freundlich model.The photocatalytic degradation here fit in with the first-order kinetic order.
