Abstract
Pilot trials of a new nanocomposite mesopore sorbent of the NCMS type have been conducted in a purification technology for slightly acidic sewage from mercury. According to the trials, the dynamic capacity with respect to mercury of the NCMS sorbent was equal to 25.6 mg/g. Atomic emission spectroscopy method with the application of a two-jet plasmatron and a registration scheme was used to receive data on the nature of quantitative distribution of mercury and associated impurity-metals (lithium, sodium, potassium, and calcium) across the layers of a sorbent load. It has been demonstrated that the NCMS sorbent concentrates preferentially mercury and potassium, and their mutual ratio is close to the formulation of K2HgI4 compound, while impurities of other metals practically do not accumulate in the sorbent.
