| 摘 要： | 在本实验中,采用正交实验方法组织实验,并进一步研究确定活性炭的活化所用的酸、碱浓度及活性炭的活化时间对砷的去除率的影响.实验研究结果表明,利用一定浓度的盐酸活化改性活性炭后对砷的去除率有一定的影响,氢氧化钠改性的活性炭对砷的去除率的影响不大.而活性炭在酸碱活化剂中的活化时间对砷的去除率有一定的影响,砷的去除率随着活性炭的活化时间的增长而逐渐增加,然后趋于平衡.

| Abstract: | The orthogonal test was used to arrange experiments to study the concentration of acid and base using the modified activated carbon,and the activation time of activated carbon effected on the efficiency of arsenic removal.The results of experimentation show that the concentration of hydrochloric acid using the modified activated carbon has great effect on the removal of arsenic while the concentration of sodium hydroxide has less effect.Arsenic removal was great affected by the change in the activation time... |
