Experimental results showed that the relative average error of the proposed method, the hydrazine hydrate gravimetry and the ammonium chloroplatinate gravimetry is -0.14%~+0.13%,-0.21%~+0.21% and -0.13%~+0.14%, respectively, and the relative standard deviation of three methods is 0.05%~0.08%, 0.11%~0.14% and 0.08%~0.09%, respectively, for Pt content from 37% to 65%. Therefore, the accuracy and precision of the proposed method are almost the same with hydrazine hydrate gravimetry, and are a little better than ammonium chloroplatinate gravimetry.
