标题
method is presented for the rapid solvent extraction of gallium (III) with o, o, s-triethyldithiophosphate. Quantitative extraction results from 4-9 M hydrochloric acid, using 100% extractant. The extract-able species is H[GaCl4]?2(C2H5 O2)2 P(S)SC2H5. 出版机构：Taylor & Francis 刊物名称：Analytical Letters 出版时间：1971 ISSN：0003-2719 数据源：报刊文摘
methylisobutyl ketone/formamide two-phase organic solvent system was utilized for the separation of thallium(III) from the elements Ga, In, Fe(III), Sn(II) and Sn(IV). 出版机构：Taylor & Francis 刊物名称：Analytical Letters 出版时间：1971 ISSN：0003-2719 数据源：报刊文摘
The Pd2+-thiourea complex formed in perchloric acid medium in the presence of NaCIO4., has been extracted quantitatively into tri-N-butyl phosphate (TBP) supported as a stationary phase on a column of Voltalef (polychloro-trifluoro ethylene). 出版机构：Taylor & Francis 刊物名称：Analytical Letters 出版时间：1971 ISSN：0003-2719 数据源：报刊文摘
The extraction of Eu(III) has been carried out from a 1 M (H,Na)Clo4 solution into different organic solvents at constant total concentration (6.67 ? 10-3 M) of the extractant, di-n-butyl-ethane-(l,2)-diphosphonic acid (H2B2-EDP). 出版机构：Taylor & Francis 刊物名称：Analytical Letters 出版时间：1971 ISSN：0003-2719 数据源：报刊文摘
Using nuclide Ru-106 the extraction of ruthenium by some usual organic reagents and various solvents has been studied with the aim to obtain informations on the complex chemical behaviour of ruthenium(IV) in diluted solutions and on the mechanism of the extraction. 出版机构：Taylor & Francis 刊物名称：Isotopes in Environmental and Health Studies 出版时间：1971 ISSN：1025-6016 数据源：报刊文摘
Es werden einfach herzustellende Gerate beschrieben, mit deren Hilfe mehrfach wiederholte Flussig-Flussig-Extraktionen schnell, unter geringem Arbeitsaufwand und mit verminderten Substanzverlusten durchgefuhrt werden konnen. 出版机构：Taylor & Francis 刊物名称：Isotopes in Environmental and Health Studies 出版时间：1971 ISSN：1025-6016 数据源：报刊文摘
eries of anion selective electrodes of the liquid membrane type have been examined with respect to selectivity characteristics. The resulting selectivity data are examined in terms of theory of liquid membrane electrodes and correlations are made with extraction constants. 出版机构：Taylor & Francis 刊物名称：Analytical Letters 出版时间：1971 ISSN：0003-2719 数据源：报刊文摘
new extraction-photometric method is suggested for the determination of microgram amounts of some thiols. 出版机构：Taylor & Francis 刊物名称：Analytical Letters 出版时间：1971 ISSN：0003-2719 数据源：报刊文摘
The effect of including charcoal during extraction on the amount of manganese brought into solution was measured on soils from the Coastal Plain, Piedmont, and Mountain physiographic regions. The presence of charcoal increased the level of Mn extracted with dilute acid by a factor of 1. 出版机构：Taylor & Francis 刊物名称：Communications in Soil Science and Plant Analysis 出版时间：1971 ISSN：0010-3624 数据源：报刊文摘
