研究了在碱性条件下，以过氧化氢为氧化剂，钼酸盐离子催化2,4,6-三氯苯酚（TCP）和五氯苯酚（PCP）的脱氯和破坏。在常温常压条件下，TCP和PCP的95%以上毫摩尔溶液在40min内可转化为co2和CO、氯化和非氯化羧酸。每个TCP最多释放2.4个氯离子，每个PCP最多释放3.5个氯离子。TOC测量表明，反应1小时后，分别有18%和11%的碳矿化成TCP和PCP。ESR测量结果表明，反应可能通过单线态氧途径进行。
The dechlorination and destruction of 2,4,6-trichlorophenol (TCP) and pentachlorophenol (PCP) under basic condition using hydrogen peroxide as the oxidant catalyzed by molybdate ions have been studied. Under ambient conditions of temperature and pressure, more than 95% of millimolar solutions of TCP and PCP can be converted to CO2and CO, chlorinated and nonchlorinated carboxylic acid in 40min. Up to 2.4 chloride ions per TCP and 3.5 chloride ions per PCP were released. TOC measurements indicated that 18% and 11% of the carbon was mineralized for TCP and PCP respectively after an hour of reaction. The results of ESR measurements suggested that the reaction possibly proceeded via the pathway with singlet oxygen.
