The kinetics and mechanism of methylene blue adsorption onto raw pine cone biomass ( Pinus radiata ) was investigated under various physicochemical parameters. The extent of the methylene blue dye adsorption increased with increases in initial dye concentration, contact time and solution pH but decr...
