摘要: 用硝酸对花生壳进行改性处理,并以其为吸附剂用于吸附废水中的磷。分别考察了pH、改性花生壳投加量、吸附时间以及磷酸盐初始浓度对吸附效果的影响。结果表明,在溶液pH为6.0、改性花生壳投加量为3.0 g、吸附时间为75 min、磷酸盐初始浓度为20 mg/L的条件下,磷的吸附率可达85.0%。
Abstract: The peanut shells that modified by nitric acid solution were used as adsorbent to adsorb phos-phorus in wastewater. The effects of pH value, the amount of modified peanut shell, adsorption time and initial concentration of phosphorus on the phosphorous adsorption rate were investigated, respectively. The results showed that when the pH value was 6.0, the addition of modified peanut shells was 3.0 g, adsorption time was 75 min and the initial phosphate concentration was 20 mg/L, the adsorption rate of phosphate could reach 85.0%.
