摘要
以龙胆紫染料废水为探针反应,评价了复合催化剂PW11Mn/PANI/SnO_2光催化性能,研究了催化剂用量、溶液的p H值和不同催化剂对光降解孔雀石绿的影响,实验结果表明:复合催化剂PW11Mn/PANI/SnO_2比SnO_2、PW11Mn和SnO_2/PANI催化活性高,经过30W紫外光照射后,其降解率达94.62%,且光催化降解龙胆紫染料为一级动力学反应。
The photocatalytic activities of composites PWH Mn/PANI/SnO2 was investigated for the degradation of gentian violet as a probe. The effect of pH , PW1, Mn/PANI/SnO2 dosage and different photocatalyst for gentian violet were discussed. Results show that the degradation rate is 94.62% under 30W UV irradiation,The activity of catalyst PW11 Mn/PANI/SnO2 is better than the SnO2, PW11 Mn and SnO2/ PANI. Photocatalytic degradation of gentian violet is the characteristic first - order reaction kinetics.
