Abstract
The sorption kinetics of heavy metal ions by organic suspension is considered in the case of a volley of wastewater into a channel flow. The characteristic time scales of the major kinetic stages of ionic sorption are estimated by using a model of matter sorption by particulate matter involving macrokinetic parameters and field data. The sorption on organic suspension and iron hydroxides is virtually instantaneous, whereas the characteristic time of sorption on clay particles is of the order of hours and days. A concept of sorption capacity of natural water is introduced. This capacity depends on the concentration of the sorbing suspension and the distribution coefficient of the dissolved forms of substances that can be sorbed, in particular, heavy metals. When the sorption capacity is small or sorption kinetics is slow, the dilution of wastewater becomes the main mechanism reducing the concentration of metal ionic forms.
