ARTICLE ANNOTATION

quote
This article provides a summary of biosorbent wastes and their sources. The conditions for modifying rice husk humus in an aqueous solution with functional groups similar to the indicated biosorbents and functional groups convenient for modification are presented. Elemental analysis of the composition of samples of mechanically cleaned rice husks, activated rice husks and modified rice husks was carried out. The physicochemical properties of the obtained biosorbent were studied . It has been established that the maximum absorption of Ni (II) ions by the biosorbent from an artificial solution under static conditions is 245.8 mg/g. The effect of solution concentration, sorption duration, and temperature on the sorption process has been studied. The amount of metal ions absorbed by the biosorbent was calculated based on the plot of the dependence of the initial and postsorption refractive indices of solutions on the concentration of the solution in a UV spectrophotometer . When studying the kinetics of absorption of identified metal ions by the sorbent, the sorption process was psevdo -first order (R2=0.8132) and psevdo -second order (R2=0.999). Hence, it was determined that the sorption process obeys the psevdosecond kinetic model.
