选择多种有机物，对Cr(6+)离子与有机物共存污染体系的光催化氧化还原协同作用研究，得出了光催化应用于消除有毒金属离子与有机污染物共存实际体系的有关信息．在酸性条件下，TiO2对Cr6+离子污染具有显著的光催化还原消除效果，还原气氛对反应影响不大，Cr6+离子的光催化还原符合L-H动力学规律．不同有机物存在表明，醇、酸及某些芳香有机物对Cr6+的光但化还原具有明显的促进作用，而一些烷烃及氯代烷烃则表现出一定的阻抑作用．这种不同影响与有机物结构紧密相关，而与其所含碳数关系不大．
A variety of organic compounds were selected to study the synergistic effect of photocatalytic oxidation and reduction of Cr (6+) coexisting pollutants with organic pollutants. The relevant information on the practical application of photocatalytic in eliminating the coexistence of toxic metal ions and organic pollutants was obtained. Under acidic conditions, TiO2 has a significant photocatalytic reduction effect on Cr6 + contamination, and the reduction atmosphere has little effect on the reaction, and the photocatalytic reduction of Cr6 + ions conforms to the L-H kinetics. The existence of different organic compounds showed that alcohols, acids and certain aromatic organic compounds had a significant promotion on the photochemical reduction of Cr6 +, while some alkanes and chlorinated alkanes showed some inhibition. This different effect is closely related to the structure of organic matter, but not to its carbon number.
