劣质硫酸铜快速检测法果树防病常须大量硫酸铜，而现有分析硫酸铜的方法对含硫酸亚铁过多的劣质硫酸铜滴定终点不明显。作者经过试验，提出一个新的速测法，可用于农村等条件不具备的单位，能快速、准确得其基本含量。其原理是ＣｕＳＯ＿４．５Ｈ＿２Ｏ溶于水后，加浓氨水...
Low quality copper sulfate rapid detection method Fruit tree disease prevention often require large amounts of copper sulfate, and the existing method of analysis of copper sulfate on sulfuric acid titanate too much inferior copper sulfate titration endpoint is not obvious. After testing, the author put forward a new rapid test method, which can be used in the units that rural areas do not have, and can quickly and accurately obtain its basic content. The principle is CuSO_4.5H_2O dissolved in water, add concentrated ammonia ...
