精细陶瓷(高级陶瓷, 高级工业陶瓷). 采用溶氧消耗法测定半导体光催化材料光催化活性的试验方法

[中文适用范围]： 本标准规定了半导体光催化物质光催化氧化水相中苯酚所消耗的溶解氧浓度的测定方法。 该方法适用于针对水污染物的半导体光催化材料的粉末测试样品或薄膜测试片。 该测试方法不适用于评估与其他基材共轭的材料，例如也可以通过光催化活性分解的有机粘合剂。 本标准适用于半导体光催化材料针对水污染物的粉末试样或薄膜试件活性的测试方法。 [外文原描述]： ISO 19722:2017 specifies the test method for determination of concentration of dissolved oxygen consumed due to photocatalytic oxidation of phenol in aqueous phase by semiconducting photocatalytic substances. The method is applicable to powder test sample or film test piece of semiconducting photocatalystic material targeting water contaminants. This test method is not applicable for evaluating the materials conjugated with other base material, such as organic binder which can also be decomposed by the photocatalytic activity. ISO 19722:2017 is applicable to the test method for the activity of powder test sample or film test piece of semiconducting photocatalystic material targeting water contaminants.
