Sorption studies of Methylene Blue in aqueous solution by optimized carbon prepared from Guava seeds (Psidium guajaval)

The aim of this investigation was to determine the adsorption behavior and kinetics of methylene blue in aqueous solution on activated carbons prepared from guava seeds by way of the two stage activation method in self-generated atmosphere using a muffle furnace. The yield and ash contents of the ac...
