有机染料废水是一个严重的环境问题。吸附和光降解是去除废水中有机染料分子的两种最常用的方法。在这项工作中，我们开发了一种简单的方法来合成CaWO 4-生物炭纳米复合材料的共沉淀法与氯化钙和钨酸钠在商业生物炭的存在下。所制备的CaWO 4-生物炭纳米复合物联合收割机结合了生物炭的吸附作用和纳米CaWO 4对染料的光脱色作用。研究了CaWO 4与生物炭的配比对罗丹明（RhB）和甲基橙子（MO）等有机染料降解的影响。与裸生物炭相比，CaWO 4-生物炭复合材料对有机染料的去除能力有所提高。本工作中开发的CaWO 4-生物炭复合材料的合成提供了一种表面技术，以提高生物炭的去除能力，它可以用于工业废水处理，以提高有机染料的去除效率。
Wastewater contaminated by organic dyes is a serious environmental concern. Absorption and photodegradation are two of the most common methods for organic dye molecule removal in wastewater. In this work, we develop a facile method to synthesize CaWO4-biochar nanocomposites by co-precipitation method with calcium chloride and sodium tungstate in the presence of commercial biochar. The prepared CaWO4-biochar nanocomposites combine the adsorption effect from biochar and photodecoloration of dyes from CaWO4nanoparticles. The influence of the ratio of CaWO4to biochar on the organic dyes including rhodamine (RhB) and methyl orange (MO) is studied. The improved organic dye removal capacity of the CaWO4-biochar composites compared with bare biochar is obtained. The synthesis of CaWO4-biochar composites developed in this work provide a facial technique to improve the biochar removal abilities, which can be used in industrial wastewater treatment to increase the organic dye removal efficiency.
