A comparative study on the catalytic influence of Cu(II), Co(II), Ag(I) and Ni(II) on oxidation of (NH4)(2)SO3 using O-2 gas

Das, P.K.; Anand, S.; Das, R.P. (Scandinavian Journal Of Metallurgy, 24(4), 1995: 152-158)

The kinetics of oxidation of ammonium sulfite using gaseous oxygen were studied in an autoclave at 373K. Kinetic equations for various catalysts such as Cu(II), Co(II) and Ag(I) were determined. The reaction rate at 373K ...
The effect of gibberellic acid (GA(3)) on the growth, photosynthetic pigment content and oil yield of patchouli (Pogostemon cablin Benth) plants grown in shade condition

Misra, M. (Acta Physiologiae Plantarum, 17(4), 1995: 367-370)

Application of 10 to 500 mg L(-1) GA(3) to shade grown patchouli plants increased the number of nodes, branches, number of green leaves, total leaf area, specific leaf fresh weight, leaf area index, photosynthetic pigment ...
APPLICATION OF GIBBERELLIN TO POGOSTEMON CABLIN PLANTS - GROWTH, PHOTOSYNTHETIC PIGMENT CONTENT AND OIL, YIELD

Misra, M. (Biologia Plantarum, 37(4), 1995: 635-639)

Foliar application of gibberellin (GA(3)) to patchouli (Pogostemon cablin Benth.) increased the plant height, number of nodes per plant, leaf fresh mass and photosynthetic pigment contents. The content of chlorophyll (Chl) ...
GROWTH, PHOTOSYNTHETIC PIGMENT CONTENT AND OIL YIELD OF POGOSTEMON CABLIN GROWN UNDER SUN AND SHADE CONDITIONS

Misra, M. (Biologia Plantarum, 37(2), 1995: 219-223)

Patchouli (Pogostemon cablin Benth.) plants grown under shade (LI) showed an increased height due to internodal elongation, leaf area, leaf area index, and chlorophyll (Chi) b, Chi (a + b) and carotenoid (Car) contents ...
BASIC ASPECTS OF NICKEL EXTRACTION FROM CHROMITIFEROUS OVERBURDEN

Swamy, Y.V.; Reddy, B.R.; Murthy, B.V.R.; Ray, H.S. (Transactions Of The Institution Of Mining And Metallurgy Section C-Mineral Processing And Extractive Metallurgy, 104, 1995: C151-C154)

Nickel oxide in an Indian chromitiferous overburden was reduced with a CO-CO2-N-2 gas mixture and the effects of various operating parameters, such as roasting temperature, time and P-CO, Were studied. An extraction of ...
KINETICS OF CUO DISSOLUTION IN DIFFERENT ORGANIC-ACIDS UNDER ROTATING-DISK GEOMETRY

Chaudhury, G.R. (Transactions Of The Institution Of Mining And Metallurgy Section C-Mineral Processing And Extractive Metallurgy, 104, 1995: C169-C171)
KINETICS OF CU(II) ADSORPTION BY PENICILLIUM SP

Mishra, S.P.; Chaudhury, G.R. (Transactions Of The Institution Of Mining And Metallurgy Section C-Mineral Processing And Extractive Metallurgy, 104, 1995: C107-C110)
RECOVERY OF ZINC FROM ACIDIC WASTE-WATER USING CHARCOAL

Mishra, S.P.; Chaudhury, G.R. (Transactions Of The Indian Institute Of Metals, 48(5), 1995: 359-362)

Adsorption studies of Zn2+ form air acidic solution was carried out using charcoal. The effect of various parameters like contact time, pH of the solution, temperature, initial Zn2+ ion concentration, pulp density and ...
SOLVENT-EXTRACTION OF COPPER FROM AN ACIDIC COPPER-IRON SOLUTION

Mishra, S.P.; Chaudhury, G.R. (Transactions Of The Indian Institute Of Metals, 48(5), 1995: 363-366)

Solvent extraction studies of copper were carried out from bioleach liquor using LIX 84. The bioleach liquor contained 0.54 g.dm(-3) and 3.8 g.dm(-3) of Cu and Fe respectively. The pH of the solution was 1.8. By using 7.5% ...
A MODEL FOR DISSOLUTION OF METAL SULFIDES UNDER OXIDATIVE AMMONIACAL CONDITIONS - ZNS-PBS-NH3-O-2 SYSTEM

Roy, G.G.; Ghosh, M.K.; Anand, S.; Das, R.P. (Transactions Of The Indian Institute Of Metals, 48(1), 1995: 15-20)

A model for the dissolution of metal sulphides under oxidative ammonia leaching conditions has been presented. The dissolution is assumed to follow surface reaction with shrinking core model. Ammonia molarity is chosen in ...
