采用本分解法,可不预先灼烧,直接用逆王水(1+1)—磷酸分解样品,并以此来抑制硫和其他有机物的干扰。试验发现,单独使用逆王水溶样时,结果略有偏高。磷酸的引入有助于样品的分解,同时能络合、掩蔽部分干扰元素,增强泡沫塑料对金的吸附能力,实验结果令人满意。
The decomposition method, without pre-burning, directly with the inverse Wang aqua (1 +1) - phosphoric acid decomposition samples, and in order to suppress the interference of sulfur and other organic matter. The test found that the use of inverse water sample alone, the results slightly higher. The introduction of phosphoric acid can help to decompose the sample, at the same time it can chelate, mask part of the interference elements and enhance the adsorption capacity of the foam to gold. The experimental results are satisfactory.
