Quantitative parameters for interaction of flavonoids-the naturally occurring antioxidants, with solvents and surfactants are determined using UV-visible absorption spectroscopy. The availability of flavonoids; kaempferol, apigenin, kaempferide and rhamnetin in micelles of sodium dodecyl sulfate (SDS) is reflected in terms of partition coefficient, K(c).(More)
The fate of trace elements (like Ca, Fe, Al, Pb, K, and Cu) in various pulses (mash, mung, lentils and red kidney beans) of Pakistan has been studied. Samples were collected from two districts (Mansehra and Rawalpindi) and analyzed by wet acid digestion method using atomic absorption spectrophotometry. Experimental results show that the intensity of heavy(More)
Conductometric behaviour of 1-alkanols (C5-C10) in organised solutions of sodium dodecylbenzenesulfonate (SDBS) is investigated. Interaction of each alkanol with anionic surfactant is reflected in terms of association constants, Kc. It is observed that self-assembly of SDBS is induced by the alkanol addition. The depression in critical micelle concentration(More)
