Studies on purification of platycodins by AB-8 macroreticular resin
Adsorption involves exposing the water to high surface areas of activated carbon or a unique macroreticular resin
to tie up organics, chlorine, and colloids from the feedwater.
Chloroform fraction was dried and further purified through HPD-400 macroreticular resins
. The purity of saponin in the final dry product was determined by ultraviolet spectroscopy and reached 80.50%.
A good representation of equilibrium data using this equation was reported for adsorption of phenolic compounds from aqueous solution onto activated carbon , and on Amberlite XAD-4 and XAD-7 macroreticular resins
