Polarographic determination of anticancer drug vitamin K3 with direct and indirect methods/application to serum and K3 injection solution
Vitamin K3 sulfite direct indirect differential pulse polarography
2011/4/6
In this work, direct and indirect methods for determination of vitamin K3 were developed using differential pulse polarography. The reaction between sulfite and the quinone (Q) form of vitamin K3 was ...
External Mass Transfer Studies during the Adsorptions of Some Dyestuffs and p-Nitrophenol onto Chitosan from Aqueous Solution
Chitosan Dyestuff adsorption External mass transfer coefficient
2010/4/20
The effect of temperature on the adsorptions of some dyestuffs [orange II (O-II), crystal violet (CV) and reactive blue 5 (RB5)] and an ideal adsorbate p-nitrophenol (PNP) by chitosan (Sigma C 3646) f...
Silver Removal from Aqueous Solution by Adsorption on Concrete Particles
Concrete Equilibrium constants Intrinsic acidity constants Silver adsorption Surface acidity
2010/4/21
The ability of concrete to remove silver from its aqueous solutions was studied. Silver removal is favored by low concentration and high pH at room temperature. The intrinsic acidity constants, averag...
