Assessment of sorption properties and kinetic reaction of phosphorus reactive material to limit diffuse pollution
Journal Title: Annals of Warsaw University of Life Sciences – SGGW. Land Reclamation - Year 2017, Vol 49, Issue 1
Abstract
Polonite® is an effective reactive material (manufactured from opoka rock) for removing phosphorus from aqueous solutions. In conducted experiments, Polonite® of grain size of 2–5 mm was used as a potential reactive material which can be used as a fi lter fulfi llment to reduce phosphorus diffuse pollution from agriculture areas. Kinetic and equilibrium studies (performed as a batch experiment) were carried out as a function of time to evaluate the sorption properties of the material. The obtained results show that Polonite® effectively removes such contamination. All tested concentrations (0.998, 5.213, 10.965 mg P-PO4·L–1) are characterized by a better fi t to pseudo-second kinetic order. The Langmuir isotherm the best reflects the mechanism of adsorption process in case of Polonite® and based on the isotherm, calculated maximum adsorption capacity equals 96.58 mg P-PO4·g–1.
