目前多采用活性炭动态吸附以分离和富集金,吸附全之活性炭纸饼则需在抽气减压下进行洗涤,此过程很繁。泡沬塑料吸附、分离和富集金非常方便,富集也很完全,但灰化处理时臭味很大。本文提出,采用自制“封闭式蒸气加热振荡无污染溶矿装置”进行溶矿,用“充碳泡沫”吸附、分离和富集样品中的金后采用无臭灰化技术进行泡沫塑料的灰化处理。不仅克服了上述存在的问题,而且仅用王水(1+1)就能使矿样分解完全,王水蒸气无排放而得到充分利用。2小时可溶矿180个,从而大大提高了分析效率。若两人一个台班,分析效率为每日60～80个
At present, the use of dynamic adsorption of activated carbon to separate and enrich the gold, activated carbon paper cake adsorption is required under the vacuum under pressure for washing, this process is very complicated. Bubble plastic adsorption, separation and enrichment of gold is very convenient, enrichment is also very complete, but when the ash treatment odor. In this paper, we propose to use a self-made “closed-end vapor-heated non-polluting solution melting equipment” to dissolve the ore and use “carbon-filled foam” to adsorb, separate and enrich the gold in the sample, Ashing of plastics. Not only to overcome the above problems, but only with aqua regia (1 +1) will be able to completely decompose mineral samples, the king of water vapor without emissions and be fully utilized. 180 hours 2 hours soluble ore, thus greatly improving the efficiency of the analysis. If two people have a class shift, the analysis efficiency is 60-80 per day
