medium using Lix series extractants have been reported[2-15]. Now, Lix 984N and M5640 are widely used as extractive reagents. Lix 984N is a mixture of Lix 860N and Lix 84 in kerosene. The active... extractive reagent was Lix 984N (Germany Henkel Corporation) with kerosene as the diluent reagent. The stripping reagent was 180 g/L H2SO4 solution. 2.2 Analytical method The concentration......
, alcohol, acid, thiourea, sulfuric acid and sodium hydroxide in analytical grade were used as main reagents in the experiments. Sodium silicate and kerosene were in industrial grade. PGA and BX were... and they were sealed. Kerosene was used as a collector, and Na2SiO3 was used as a flocculant. In addition, the dosage of kerosene was fixed, as the same as that in the concentrator of Dexing copper mine......
in the organic phase consisting of TBP and kerosene will be investigated. In addition, the distribution coefficients and extraction constants of the metal-organic comlexes should be determined. To get... of bismuth via precipitation stripping with TBP have been published. 2 Experimental 2.1 Reagent and solutions Tributyl phosphate (TBP) was used as received without futher purification. Kerosene was used......
Cyanex 923 in kerosene followed by stripping with 1 mol/L HNO3. In the meantime, yttrium was recovered upon extraction with 0.2 mol/L DEHPA in kerosene followed by stripping with 2 mol/L HCl. The purities... possible to tune the physicochemical properties of ILs [26]. Extractions of many metal ions were reported using different ILs [27-39]. Different forms of Aliquat 336 diluted with kerosene were applied......
] found that the bacteriostasis order of the organic matter was as follows: 260# kerosene+1.5% LIX 984N＞260# kerosene＞circulated organic phase sampled from factory＞octanol + 1.5% LIX 984N＞octanol. WATLING... of the extractant on L. ferriphilum, but according to the research of MAZUELOS et al [6], a 15% mix of LIX 64 in kerosene decreased the iron-oxidation rate of L. ferrooxidans in mixed cultures......
beaker using the pretreated TBP (diluted in kerosene) and 5.0 g the pretreated dry polymeric resin. To verify the maximum impregnation, the major factors affecting the solvent impregnation were studied... to polymeric resin S/R ratios from 3.0 to 6.0 where the solvent concentration was 80% TBP in kerosene and impregnated for 24 h; 3) phases contact time from 1.0 to 48 h where the solvent concentration of 80......
with 25% D2EHPA in kerosene, followed by selective precipitation with oxalic acid. TZANETAKIS and SCOTT[2,7] used D2EHPA to extract and separate the rare earth elements after leaching by hydrochloric... extractant for rare earth whose organic phase is composed of 20% PC-88A+80% kerosene. The solvent extraction was carried out in mixer-settler, in which the capacity of mixing chamber and 30-stage clarifying......
or sulphonated kerosene) and a sort of modifier with basic group (TBP or mixed-alcohol). It is interesting, in this extraction system, Au(CN)-2 could be highly selectively and quantitatively extracted..., and the initial concentration was 5.077×10-3 mol/L containing Au 1.002g/L. Sulphonated kerosene was obtained by refining the commercial kerosene. Tri-butyl-phosphate(TBP), cetyl trimithyl ammonium......
heptahydrate (analytical reagent grade) with deionized water. The pH of all Co(II) solutions was adjusted to 3.50 by adding dilute H2SO4. DDPA was produced in-house. Sulfonated kerosene was used as the diluent. The sodium salts of DDPA (Na-DDPA) were prepared by adding stoichiometric amount of 10 mol/L NaOH solution to the extractant in kerosene and stirring the phases to form a single phase. 2.2......
are found for crude oil, kerosene and PCE, which infiltrates faster in sandy textures soils than in loam soils [4, 26]. Gravity and capillary forces control the fluid infiltration [27] and the effect... the larger pore spaces and require less time to pass through the soil. The role of water films was also found to reduce the resistance to the flow of kerosene in sand, and the different effects......
