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. But it is rapid, economic, secure, easy to operate and environmental friendly.

结果表明：测定37%~65%的Pt含量，本法、氯铂酸氨重量法、水合肼还原重量法的相对平均误差分别为-0.14%~+0.13%、-0.21%~+0.21%、-0.13%~+0.14%，相对标准偏差分别为0.05%~0.08%、0.11%~0.14%、0.08%~0.09%，故本法的准确度和精密度与水合肼还原重量法的基本一致，较氯铂酸氨重量法的略好；但本法消解快速、节能、安全，操作简便，对环境污染程度小，适宜推广运用。

A modified analysis method based on the determination of ozone—indigo disulphonate spectrophotometer(GB/T 15437-1995) in gas phase has been developed to detect the concentration of ozone in liquid phase. An analytical condition of λmax=612～615 nm,ε=20 000 L/, pH 2 is obtained by the titration of indigo disulphonate. Compared with potassium iodide method,it shows a higher precision and accuracy,CV＜3.0%. The results also prove that blank experiment will bring about 5.0%systematic error.
