| Abstract: | There had different effect of composite flocculation and cationic ion exchange resin in the isolation and treat of wastewater. To combine these two methods for pretreatment of Cr 6 before determination. The best reaction condition was determined after research. Results indicated that this method had high colourity decrease, good isolation effect, high anti-disturbance to disturbing ion, good repeatability, high accuracy, and was simple and easy to operate. |

| Keywords: | Composite flocculation Cationic ion exchange resin Pretreatment Industry wastewater Cr 6 |
