Sulphate was determined in various kinds of environmental samples using a continuous-flow system, a flow-injection system or a flow-through titrimeter. The reagents in the three cases consisted basically of DMSA(III), KNO3 and Ba(ClO4)2. The results of the three methods were evaluated statistically. A comparison of the three methods is given. The advantage of the DSMA(III)-methods is shown in a comparison with the commonly used thorin method.
