摘要
研究了铁 (III) -草酸配合物在可见光及太阳光照射下 ,对活性染料的光解降解作用。结果表明 ,在pH=4.0、Fe(III)/H2C2O4=0.060mmol/L/2.88mmol/L(草酸分2次加入 )、光照3h的条件下 ,20mg/L的活性红的降解率为97.5%。溶液 pH值、铁与草酸浓度比和活性染料浓度均对降解效果产生影响。
The experiment of photochemical degradation of the active dyes was conducted in aqueous solution containing Fe(III)-oxalate complex irradiated with visible light and sunlight.The result showed that under the condition pH=4.0,Fe(III)/H2C2O4=0.060 mmol/L/2.88 mmol/L(oxalic acid was divide into bisection and add in),the degradation rate of 20 mg/L the active red X-3B dye was 97.5% in 3 h sun light irradiation.It is found that pH,concentration ratio of Fe(III)to oxalate and initial concentration of the phenol have some effect on the degradation rater.
