本方法是用活性炭吸附,碘量法测金,在其吸附后的滤液中测定银和铜。分析方法:称样10—30克,低温焙烧30分钟,以盐酸30毫升溶解,再加1:1王水100毫升加热溶解,安装过滤吸附装置是用圆简型漏斗,加入1:1活性炭滤纸浆,活性炭量1.0—1.5克,层厚约10—15毫米,放500毫升抽滤瓶上,以两通旋塞使其与抽气管连接,吸附柱上加布氏漏斗。抽滤分解好的矿样,用5％热盐酸水冲洗烧杯5次,
This method is activated carbon adsorption, iodometry gold, silver and copper in the adsorption of the filtrate after its determination. Analysis: Weigh 10-30 grams, roasted 30 minutes at low temperature, dissolved in 30 ml of hydrochloric acid, plus 1: 1 aqua regia 100 ml heated to dissolve, the installation of filtration adsorption device is a simple round funnel, add 1: 1 activated carbon filter Pulp, the amount of activated carbon 1.0-1.5 grams, layer thickness of about 10-15 mm, put 500 ml suction bottle, the two-way cock to make it connected with the exhaust pipe, adsorption column with Buchner funnel. A good sample of mineral decomposition and filtration, rinse the beaker 5 times with 5% hot hydrochloric acid water,
