摘要
采用紫外-可见分光光度法,研究经无水乙醇提取后的农业稻草提取剂溶液对甲基紫的吸附作用,探讨在不同pH值、初始浓度和吸附时间条件下,不同用量的吸附剂对甲基紫溶液的吸附效果。结果表明,当pH为10.34时,400 mg的稻草吸附剂对48.29 mg/L,15mL的甲基紫吸附30 min去除率达72.1%。
The adsorption behaviors about methyl violet with rice straw sorbent were studied.After adsorption,the concentration of methyl violet in filtrate was determined by ultraviolet and visible spectrophotometry,the adsorption rate was calculated.The influenceable factors,including pH value,concentration of adsorbate,absorption time and amount of adsorbent were studied.The adsorptive ratio of methyl violet was 72.1% under such experimental conditions as:(a) the concentration of methyl violet was 48.29 mg/L,(b) the volume of solution was 15 mL,(c) pH value was 10.34,(d) the dosage of rice straw sorbent was 400mg,and(e) the reaction time was 30min.
