It is the reason of the adsorption capacity degression that the residual adsorption capacity is relatively more in the desorption process by water. 洗涤脱附过程中残留吸附容量较大是活性炭吸附容量下降的根本原因。
The desorption experiment found that Cd was easier to be desorbed than Cu and most of the metals desorbed in the first 3 hours. 而铜短期间内之脱附比例与水溶态及交换态之和呈正相关，镉则与最大吸持量呈正相关。
