In this Work the combination of catalytic chemical reaction with the three-hole ring oven technigue is adopted to determine arsenic in drinking water to 0.02 PPm As molybdate ion liberated from a complex compound of ammonium arsenate and molybdenum oxide acts as a catalyst for the reaction of H_2O_2 (hydrogen peroxide) with a guontitative amount of KI. The starch solution is used as color reagent Micro-extraction procedure is also used for separation and concentration of arsenis in the sample solution.

众所周知,砷是对人体有害的痕量元素之一。砷及其化合物被饮用后,可由肠胃道、汗腺、唾液腺、乳腺排出体外。砷在体内能损坏肝脏,致使发生肝硬变。特别能通过胎盘循环而影响胎儿等。因此控制和监测饮水中的微量砷,显得十分重要。砷的测定,通常是用比色法、极谱法、原子吸收来完成。用环炉技术测定饮水中的痕量砷,在文献中还未见到报导。本文用动力催化反应于环炉技术,由砷钼酸铵中释放出的钼对双氧水和碘化钾定量的催化作用,用淀粉为显色剂。并采用微量萃取分离和浓集的方法,以测定饮水中0.02PPm砷。

A method for successive determination of micro amounts of phosphorus and arsenic in molybdenum oxide and ammonium molybdate has been developed by spectrophotometry.

After extration of phosphomolybdic and arsenomolybdic acid with suitable extractant,and reduction,the spectrophotometric determinations are taken place...

A method for successive determination of micro amounts of phosphorus and arsenic in molybdenum oxide and ammonium molybdate has been developed by spectrophotometry. The method is based on the reaction of phosphorus and arsenic with ammonium molybdate forming phosphomolybdic and arsenomolybdic acid in 0.6—1.2 mol/L and 1.0—1.6mol/L HNO medium respectively. After extration of phosphomolybdic and arsenomolybdic acid with suitable extractant,and reduction,the spectrophotometric determinations are taken place in aqueous phaseatter stripping.The method is simple in operation with high sensitivity. Molar absororption coefficient is 1.54×10~4(P) and 2.24×10~4 (As). The concentration ranges for As and P are both from 1 to 100 ppm with detection limit 1 ppm and relative standard deviation 7.9—26%. d

In this paper. the solubilities of molybde num sulfide, molybdenum oxide and metallic molybdenum in Ni-Mo matte have been studied in bromine water-hydrogen peroxide, cyanidebromine water, ferric chloride and solution of sodium-carbonate. The experiments have also been centred on the leaching metallic molybde num with FeCl_3, solution. An analytical proce dure was devised, namely, first, the molybdenum oxide is leached with 15% Na_2CO_3soln..then the metallic molybdenum is leached with 8%. FeCl_3 in 1 mol L HCl and lastly. molybdenum sulfide is determined after fusing the residue with Na_2 O_2 The comparison of analytical results by present method to those by electron probe-optical image verified that the method is accurate and applied satisfac torily to chemical phase analysis of molybdenum in the samples like Ni Mo matte.
