| 摘 要： | 以不锈钢作阴极,用电化学方法,比较了用石墨和钛基二氧化铅作阳极对废水中铜的去除效果,发现后者效果更佳.实验证明:pH值越低、温度越高、电流密度越大,铜去除率越高.数据还显示:无缓冲剂时,反应液的pH值随反应进程下降；加入磷酸缓冲液,溶液酸化受阻,不利于铜的去除.利用无缓冲剂时溶液随反应进程酸化的特点,在温度为30℃和电...

| Abstract: | Using stainless steel as the cathode and electrochemical method,we compared the copper removal rates of the graphite anode and Ti/PbO2 anode for wastewater.The results indicate that the Ti/PbO2 anode has better copper removal effect.In detail,lower pH,higher temperature and denser electric current can bring out higher copper removal rate.In addition,without buffer,the pH value of the reactant solution will decrease along with the reaction progressing.To the contrast,phosphate buffer may restrain the copper ... |
