摘要： 对用聚合前驱体溶液通过热分解法制备的Ti/SnO2+Sb2O3/PbO2电极在硫酸溶液中Cr3+电化学氧化的电化学性能进行了研究. 分别测定了以Ti/SnO2+Sb2O3/PbO2和PbO2为阳极，硫酸介质中Cr3+电化学氧化过程的极化曲线、抗腐蚀性以及不同操作电流密度、Cr3+浓度、反应温度、硫酸浓度下的电流效率. 实验结果表明，聚合前驱体溶液通过热分解法制备的Ti/SnO2+Sb2O3/PbO2电极与PbO2电极相比具有更高的电催化活性和抗腐蚀性.

Abstract: The pseudomonas delafieldii strain R-8 and Rhodococcus erythropolis N1-36 were used to remove the sulfur from hydrogenated diesel oil. Both strains utilize the organic sulfur compounds from diesel oils with approximate activities. Surfactants can increase the desulfurization rate. When agitating rate was 250 r/min with Tween80 present, the strain can remove 72% of the organic sulfur from low sulfur diesel oil (S<300 mg/L) in 72 h. But when sulfur concentration was higher than 1000 mg/L, the sulfur removal rate of diesel oil by strain R-8 is very low.
