A low grade chalcopyrite ore was leached with H2O2/(NH4)2SO4 and the leach liquor contained 42.96 mol m copper, 3.52 mol m zinc and 11.23 mol m magnesium. From this leach liquor separation of copper was carried out with supported liquid membrane using LIX84I as mobile carrier. Celgard 2400, a microporous polypropylene film was used as the solid support for the liquid membrane. The effect of pH ...

The present investigation describes the production of acid proteases by Penicillium griseoroseum IH-02 using solid-state fermentation technique. The enzyme biosynthesis was maximum (8.2 U/ml) when fermentation was carried out on a substrate containing soybean meal and wheat bran mixed at a ratio of 3:1 and moistened with D4 diluent. The substrate to diluent ratio was found to be optimum at 1:2....

Liquid–liquid extraction and liquid membrane transport behavior of tetravalent actinide ions viz. Th(IV), Np(IV), Pu(IV) were investigated for the first time using a diglycolamide (DGA) based dendrimer with tris(2-aminoethyl)amine (TREN) scaffold as organic extractant. The generation 1 six DGA pendent moieties (termed TREN-G1-DenDGA) extracted Np(IV) more effectively than other two ions, trend ...

Flotation tailings from copper production are deposits of copper and other valuable metals, such as Mo, V and U. New hydrometallurgical technologies are more economical and open up new possibilities for metal recovery. This work presents results of the study on the extraction of copper by mixed extractant consisting p-toluidine dissolved in toluene. The possibility of simultaneous liquid-liquid...

The results of studying the physical properties a deep eutectic solvent based on choline chloride and sulfosalicylic acid have been presented. A phase diagram for this two-component mixture has constructed, dependences its density refractive index temperature studied first time. molar refractivity under study calculated. possibility using as an extractant recovery metal ions in solid–liquid sys...

A macrocyclic trinuclear complex of (1,3,5-trimethylbenzene)ruthenium(II) bridged by 2,3-dioxopyridine was synthesized, and the extraction properties for lithium and sodium picrates were investigated in a dichloromethane/water system at 25 degrees C. The complex was found to have extremely high extractability and selectivity for lithium picrate; the logarithmic values of the extraction constant...

In this work, we analyze the control properties of thermally coupled reactive distillation sequences and thermally coupled extractive distillation sequences in comparison with conventional reactive and extractive distillation configurations. All sequences have been designed using a multi objective genetic algorithm with restrictions. We study the theoretical control properties of those schemes ...

In this study, lead sulfide (PbS) films were grown on Fluorine-doped TinOxide (FTO) glass substrate by thermal evaporation in a horizontal furnace toinvestigate carrier gas effect on structural, morphological, elemental, optical, electricaland photovoltaic properties of PbS. X-ray diffraction (XRD) patterns confirmed theformation of cubic polycrystalline PbS particles fo...

Introdution: Common cancer treatment methods have many side effects. Therefore, the use of new methods for drug delivery to cancer cells is necessary. In the present study, nano formulations of lipid carriers containing doxorubicin have been synthesized and its physicochemical properties have been investigated. Methods: The present study was an experimental study. The liposomal systems were sy...
