The invention discloses a method for determining content of seawater carried in turbine oil. A dissolution-elution method is adopted and the method for determining the content of the seawater carried in the turbine oil comprises the steps of extracting chloride ions Cl<-> into demineralized water from the seawater by mixing, dissolution and elution of oil and the demineralized water, conducting determination, judging whether the seawater is completely removed from the oil according to the content changing of the Cl<->, and representing the degree of the pollution caused by the seawater to the oil, thus realizing the quantitive determination on the seawater carried in the oil. The method can be used for determining the seawater carried in the oil. Isovolumetric testing oil and the demineralized water which is boiled are mixed and heated to certain temperature; at the temperature, shaking elution and standing layering are conducted; water extract is released; titration is conducted by using AgNO3 solution with
