以粉煤灰为载体,在粉煤灰上进行改性,经过掺杂,煅烧后制成为一种新型光催化剂,然后利用该催化剂再外加光照的情况下降解罗丹明B废水。并用紫外-可见光分光光度计测量罗丹明B的浓度,对数据进行分析,研究对废水的处理效果。通过光催化降解实验,研究表明: pH=7,改性粉煤灰投加量为0.2 g,罗丹明B起始浓度为2 mg/L,在可见光照射120 min后,罗丹明B的降解率达到98.77%。
以粉煤灰為載體,在粉煤灰上進行改性,經過摻雜,煅燒後製成為一種新型光催化劑,然後利用該催化劑再外加光照的情況下降解囉丹明B廢水。併用紫外-可見光分光光度計測量囉丹明B的濃度,對數據進行分析,研究對廢水的處理效果。通過光催化降解實驗,研究錶明: pH=7,改性粉煤灰投加量為0.2 g,囉丹明B起始濃度為2 mg/L,在可見光照射120 min後,囉丹明B的降解率達到98.77%。

Drift fly ash as the carrier, the fly ash was modified on the fly ash, a new type of photocatalyst was successfully made by doped and calcined, then dealt with dyeing wastewater with light. To research effect of wastewater treatment using UV-visible spectrophotometer to measure the concentration of dyeing wastewater and analysis data. Through the experiment of photocatalytic degradation, it found that pH was closed to 7, the dosing quantity of modified fly ash was 0. 2 g, and the concentration of rhodamin B was 2 mg/L, the degradation rate of rhodamin B reached 98. 77%during 120 min under visible light.
