Dynamics modeling of multicomponent metal ions’ removal onto low-cost buckwheat hulls

摘要: The process of adsorption from water solutions containing a ternary system Cu (II), Zn and Ni (II) ions onto buckwheat hulls as biosorbent was considered. sorption capacity for determined in equilibrium batch experiments. kinetics equation corresponding to the mechanism metal with adsorbent assumed. A new method modeling packed column presented. partial differential equations describing mass balance, due assumption properly defined variable, transformed into ordinary nonlinear equations, which enables identification object parameters. sorbent, isotherms, were used dynamics modeling.
