«Evaluation of the Effectiveness of Nanoporous Material Obtained by Activation of Coffee Sludge»
371–380 (2019)
PACS numbers: 61.43.Gt, 81.05.Rm, 81.05.U-, 81.07.Wx, 81.20.Wk, 83.50.Uv, 83.80.Fg
Samples of activated carbon are fabricated from powdered coffee sludge. The characteristics of porous structure of nanoporous material (with BET specific surface area of 835 m2/g, mesopores’ specific surface area of 230–300 m2/g, total pore volume of 0.5–0.6 cm3/g) are studied. Sorption properties of marker-substances are evaluated. The selectivity of samples with respect to heavy-metal ions is investigated that proves the expediency of use of such a material for the treatment of industrial effluents.
Key words: coffee sludge, physical activation, porous structure, surface area, sorption of heavy metals.
