电位滴定法测定拌种灵含量

Determine the Seedvax Content in the Potential Titration

用电位滴定法分析 4 0 %拌种双可湿性粉剂中拌种灵的含量 ,比结晶紫为指示剂的非水滴定法终点明显。

The terminal point is more obvious and the accuracy is higher determining the seedvax content of 40% seedvax thiram WP in the potentiometric titration than in the non aqueous titration with the Crystal Violet as the indicator.
