The results for aqueous solution
of NaCl can be considered as expected.
The test cell was designed to create a thin film of the aqueous solution
between the hydro-phobic microporous membrane and the back, made of acrylic glass, in which a gasket ring is used to control the channel depth.
Several workers have reported on the potential use of agricultural by-products as good substrates for the removal of metal ions from aqueous solutions
The densities [rho] of aqueous solutions
were measured with the help of a 15 x [10.sup.-6] [m.sup.3] double arm pycnometer.

In the presence of PEG, there is an increase in the molar extinction coefficient as compared to the value determined for the dye in aqueous solution
(about 31600 [M.sup.-1] [cm.sup.-1]): the value for PEG-400 (400 mg/mL) is about 35800 [M.sup.-1] [cm.sup.-1] and that for PEG-12000 (400 mg/mL) is about 36100 [M.sup.-1] [cm.sup.-1].
