将20 mg 光催化剂样品放入25 mL的亚甲基蓝水溶液中，避光条件下

将20 mg 光催化剂样品放入25 mL的亚甲基蓝水溶液中，避光条件下离心搅拌90 min，取样后放置在日光灯条件下继续搅拌，每隔20 min 取样一次，将取出的样品置于离心机中，离心分离15分钟后，取上部清液置于石英比色皿中，用紫外可见分光光度计检测亚甲基蓝的吸光度(检测波长为664nm)。通过At/A0计算亚甲基蓝的降解率.

結果 (英文) 1:

Will 20 mg light catalyst samples into 25 mL of Asia methyl blue water solution in the, avoidance light conditions Xia centrifugal mixing 90 min, sampling Hou placed in fluorescent conditions Xia continues to mixing, each across 20 min sampling once, will removed of samples placed centrifugal machine in the, centrifugal separation 15 minutes Hou, take upper Qing liquid placed quartz than color dish in the, with purple outside visible points light photometer detection Asia methyl blue of suck photometric (detection wavelength for 664nm). Rate of degradation of methylene blue by At/A0 computing.

結果 (英文) 2:

The 20 mg photocatalyst sample into 25 mL of methylene blue solution, stirred under dark conditions centrifuged 90 min, the sample is placed under fluorescent conditions continue stirring every 20 min sampling time, the sample is placed in a centrifuge to remove After centrifugation for 15 minutes, take the upper supernatant was placed in a quartz cuvette with a UV-visible spectrophotometer absorbance of methylene blue (detection wavelength of 664nm). By At/A0 calculated degradation rate of methylene blue.

結果 (英文) 3:

The water of methylene blue solution 20 mg photocatalyst samples into 25 mL, avoid light conditions of centrifugal stirring for 90 min, after sampling place and continue to stir in the daylight lamp condition, every 20 min sampling time, the sample is placed in the centrifuge extraction, centrifugal separation after 15 minutes, take part in the quartz than liquid the color matching dish, UV visible spectrophotometer absorbance detection of methylene blue (detection wavelength at 664nm). Through the calculation of At/A0 degradation of methylene blue
