The scale inhibition performance of different antiscalants,PESA,PASP,DEPTMP and SHMP were determined by measuring the maximum relative degree of supersaturation of BaSO₄ under the same antiscalant concentration via a method based on conductivity titration.The result indicates the sequence of scale inhibition performances is PESA> PASP> DEPTMP> SHMP,which is the same as that obtained by static method.Comparison between the two methods demonstrates that the conductivity titration method is more reliable.In addition,it shows that the conductivity titration method is a fast,easy,convenient,good repeatable technique,which can also be used to evaluate the synergistic inhibiting effect of antiscalants on preventing BaSO₄ precipitation.
