METHOD OF ADSORBING IONS FROM SOLUTIONS Russian patent published in 1997 - IPC

Abstract RU 2091317 C1

FIELD: waste water treatment. SUBSTANCE: adsorption of ions from solutions is effected with simultaneously controlling pH. Deviation of pH from its optimal value depending on adsorption time is maintained according to following relationship: ΔpH=ΔpH_о·exp(-k·t^m) where ΔpH is target deviation; t adsorption time; ΔpH_о maximum deviation of pH from its optimal value at zero time; k and m coefficients determined from experimental data. EFFECT: speeded up adsorption process due to improved kinetic characteristics. 4 dwg, 1 tbl
