| Abstract: | The removal of excessive Pb 2+ , which were brought in the chrome yellow production and the material of the poduction the leachate of chrome dreg, by rectorite adsorbent has been investigated with the batch method. The experimental result shows that, when pH is between 5.6 and 7.3, the reaction time is 90 min, and the ratio of adsorbent to water quantity is 24 g/L, the mass density of Pb 2+ is reduced from 2.5 mg/L to 0.05 mg/L and removal rate can receive 98%, which comes up to the standard of GB 8978\|1996. |
