【 摘 要 】

In order to find better heavy metal absorption material, this modification by heating bamboo shoots superfine powder at 50 °C with 5, 30 and 90 min. The effect on the absorption of Pb2+and Cd2+was determined through scanning electron microscopy (SEM) and infrared spectra (FTIR). The results showed that the heating time of 30 min, its absorption of Cd2+and Pb2+was best, and the highest absorption Cd2+and Pb2+were 56.46% and 74.18%, respectively. The heating time for 5 min and 90 min, absorption rate of the kinds of ions was lower than those modified.
