研制了一台流动注射测金装置。该装置由一台四道蠕动泵、两支旋转阀，一支８５３１纤维分离富集柱和有关电路组成一个整体，靠蠕动泵自动输送试样溶液，酸洗液和金洗脱液，使金在Φ３×４０ｍｍ的微型纤维柱上富集，由控制电路控制旋转阀切换自动完成柱平衡，进样，洗涤，洗脱过程，金洗脱液自动送入原子吸收分光光度计测定金。８５３１纤维是金的良好吸附剂，具有选择性容量大的优点。试样经王水分解后可直接进样测定。该装置与原子吸收分光光度计联用测定金。金的特征浓度可达０．６ｎｇ／ｍＬ每小时可测定４０～６０次。用本装置分析０．１６μｇ／ｍＬ金溶液，ＲＳＤ为０．８％。用于分析化探样品，铜精矿，电解铜等试样中金，得到满意的结果。
Developed a mobile injection gold device. The device consists of a four peristaltic pump, two rotary valves, a 8531 fiber separation and enrichment column and the circuit composed of a whole, by peristaltic pump automatic delivery of sample solution, pickling solution and gold eluent, the gold In the Φ3 × 40mm microfiber column enriched by the control circuit control rotary valve switch automatically complete column balance, injection, washing, elution process, the gold eluent was automatically sent to atomic absorption spectrophotometer determination of gold. 8531 fiber is a good adsorbent of gold, with the advantages of large selective capacity. The sample can be directly injected into the sample after being decomposed by aqua regia. The device with atomic absorption spectrophotometer assay gold. The characteristic concentration of gold up to 0.6ng / mL can be measured 40 to 60 times per hour. 0.16μg / mL gold solution was analyzed by this device with a RSD of 0.8%. For the analysis of geochemical samples, copper concentrate, copper and other samples of gold, get satisfactory results.
