ABSTRACT
Objective To establish a rapid determination method for sulfate in water. Methods In the weak acid solution, sulfate connected with barium chromate into sulfate barium and chromate. Surplus barium chromate precipitated when adding the mixture of CaCl2 and NH3?H2O. The chromate replaced by sulfate was detected at wave length of 420 nm. Results The RSDs were 1.8%-6.8% and the recovery rates were 98.9%-101.0%. Conclusion The method was rapid, simple and its sensitivity and accuracy can meet the requirement of standard examination methods for drinking water.
