batch method of operation

The method can employ scheme of batch operation or continuous recycling, which is adapted for industry utilization.

该方法可采用分批式实施，也可采用连续式的回收方案，适用于工业应用。

The results indicate that using this method to analyze one batch of samples only needs 2 h, the cost of dissolved reagent is low and toxicity small, and the operation is simple and fast too.

结果表明，采用该方法分析一批样品只需2 h，所用溶解试剂成本低、毒性小，且操作简单、快速。

So the method has merits of wide liner range, low cost, little disturbance and easy work. It fits batch operation well.

此方法线性范围较宽，干扰小，操作简单，低成本，适合于大批量样品测量。
