The PEG used in this study was PEG-3000
(average molecular weight, 3000). Stock solutions
of 30% (w/w) PEG were prepared by dissolving
of suitable quantity of PEG in deionized water.
The stock solutions of inorganic salt at different
values (10%, 15%, 20%, and 25% (w/w) KCl)
were prepared by dissolving the required amount
