摘要
以狐尾藻为原料,多聚磷酸为活化剂制备活性炭,用于吸附溶液中的Pb(Ⅱ).并利用扫描电子显微镜(SEM)、傅里叶红外光谱(FTIR)、Zeta电位、热重(TG)和比表面积测定仪(BET)对产品进行表征.结果表明,在多聚磷酸质量分数为45%,活化温度为300℃时,所制备的狐尾藻活性炭对Pb(Ⅱ)的吸附率可达到91.75%.
Activated carbon was prepared from Myriophyllum verticillatum as raw material and polyphosphoric acid as activator, and used to adsorb Pb（Ⅱ）. The activated carbon was characterized by scanning electron microscopy（SEM）, Fourier transform infrared spectroscopy（FTIR）, Zeta potential, thermogravimetry（TG） and Brunauer-Emmett-Teller（BET）. The results showed that the activated carbon of Myriophyllum verticillatum prepared on the polyphosphoric acid quality score of 45 % and the activation temperature was 300 ℃ reach high adsorption rate of Pb（Ⅱ） and the adsorption rate is 91.75 %.
