摘　　要：为了探讨粉煤灰去除重金属镉的最佳试验条件,以粉煤灰的投加量、吸附pH值、吸附时间、吸附温度为考察因素,以废水中镉的吸附量为测定对象,进行了试验。试验表明:在粉煤灰的用量为1.5 g,废水p H值为4,温度为30℃的试验条件下吸附60 min,废水中镉的去除率可以达到82.39%。In order to explore the best test conditions for the removal of heavy metal cadmium by fly ash,the fly ash dosage, adsorption pH value, adsorption time, adsorption temperature as factors, it makes the adsorption amount of cadmium in wastewater as the test object. The results show that when the dosage of fly ash is 1.5 g, the pH value of waste water is 4, and the temperature is 30℃, the removal rate of cadmium in waste water can reach 82.39%.
