This review deals with the chemical phase analysis for mineral and metallurgical products from the publications in China from 1982 to midof 1986, covering three aspects: monograph and conference, chemical phase analysis for elements and others. This paper comments mainly the present state of chemical phase analysis for thirty-one elements.

本文综述了在1982年至1986年国内矿石及冶金产品的化学物相分析发展概况。综述包括专著与会议、各元素的化学物相分析以及其它。主要评述了铝、银等31个元素的化学物相分析方法近几年的发展状况。

The colour reaction of Ga(Ⅲ) with 5-Br-DMPAP has been studied in acidic solution. The apparent molar absorptivity is 1.15×10~5l·mol~(-1)· cm~(-1) at 560 nm. The molar ratio of Ga(Ⅲ) to 5-Br- DMPAP is estimated to be 1:2. Cation interference can be eliminated by extractive chromatography with n-butyl acetate from 6M HCl medium in the presence of TiCl_3 solution as a reducing agent. This method has been applied to the determination of micro amount of gallium in certain metallurgical products with satisfactory...

研究了在酸性溶液中Ga(III)和5-Br-DMPAP的显色反应。表观摩尔吸光系数在560纳米处为1.15×lO~5l·mol_(-1)·cm_(-1)。Ga(III)与5-Br-DMPAP的摩尔比为1比2。在6MHCL溶液中,以TiCl_3作还原剂,用乙酸丁酯萃取色谱分离来消除阳离子的干扰。用于某些冶金产品中微量镓的测定,结果满意。

A new systsm for polarographic determination of Cl~- is reported. The determination of Cl~- has been studied in 0.1% HCOOH-1×10~(-3)% thymol blue-0.5% NH_4NO_3-0.2% HF-0.2% HNO_3-2.5×10~(-3)% Triton X-100 medium by oscillopolarograph model JP-1A. In the new system,second derivative anodic wave of Cl~- appears at 0.05V (vs. Ag-Hg), the determination of Cl~- is in the range of 5ppb to 20ppm,and the detection limit is 1 ppb. This method has been used for quick determination of Cl~- in water, soil, ores and metallurgical...
