| 摘 要： | 研究了电子束辐照降解锌氰络合物溶液,考察了总氰初始浓度、pH值、锌氰摩尔比对总氰的 降解效率的影响.实验结果表明,在相同的辐照剂量下,初始浓度越低越有利于锌氰络合物溶液总氰的彻底降解,锌氰络合物总氰浓度高其降解效率更高;电子束辐照降解锌氰络 合物溶液符合一级动力学方程;在相同的辐照剂量下,随着pH值和锌氰摩尔比降低,锌...

| Abstract: | This paper studies the degradation of zinc-cyanide complex in gold-leaching wastewater by the E-beam radiolysis and investigates the effects of initial concentration,pH and the ratio of Zn and CN on the degradation.The results show that under the same radiolysis dose,the lower the initial concentration,the higher the degradation efficiency;the higher the total CN-,the higher the degradation efficiency of TCN.The decomposition kinetics of zinc-cyanide are consistent with the pseudo first order reaction rate ... |
