粒子电极制备条件对三维电催化处理嘧啶醇的影响
Influence of particle electrodes preparing conditions on the treatment of 2-diethylamino-6-methyl-4-hydroxypyrimidine by three-dimensional electrocatalytic
摘要
Abstract
A series of particle electrodes were prepared by solid phase calcination method using pottery clay as substrate,mental oxide as active component. The catalytic activity of particle electrodes were investigated by the treatment of 2-diethylamino-6-methyl-4-hydroxypyrimidine simulated wastewater under three-dimensional electrocatalytic oxidation conditions. When the ratio of copper oxide and zinc oxide was 0.25 mole and 0.1 mole per Kilogram Pottery Clay,respectively,calcined temperature had been kept at 1000 ℃ for 2h , the activity of prepared particle electrode was the highest. The 2-diethylamino-6-methyl-4-hydroxypyrimidine removal rate and CODCr removal rate was 83.45%and 35.17%,respectively,under cell voltage 15V,initial pH 3,electrode span 6cm,supporting electrolyte 30g/L,airflow 40L/h,150 min after the treatment,and the particle electrode indicates high catalytic stability. The study on degradation mechanism shows that the main degradation reaction of the 2-diethylamino-6-methyl-4-hydroxypyrimidine is the opening of pyrimidine ring into small nitrogen-containing compound,while the mineralization rate of the products after pyrimidine ring is destroyed is relatively low.关键词
