    Microporous-mesoporous activated carbons from 5 different types of agro-industrial wastes were produced using the chemical activation with ZnCl2 and carbonization at mild conditions of 600 °C, comprehensively characterized and investigated for removal of methylene blue in aqueous solution, a model large molecular size organic pollutant. External part of the mango pit (mango seed husk) was used for the production of activated carbon for the first time. Despite the raw agro-materials exhibited significantly different porosity, all produced activated carbons possessed the well-developed microporous-mesoporous structures showing high surface areas and micropore volumes. It was revealed that the pore-size distribution of raw agro-material is more important property in developing of microporous-mesoporous structure of produced ACs than their overall porosity. All produced activated carbons adsorbed MB, reaching in most cases of 100 % removal from the aqueous phase.
