Glauconite as a sorbent of 4-nitrophenol

The sorption properties of glauconite from Beloozersk deposits (Saratov region) for 4-nitrophenol (4-NF) have been investigated. The effect of glauconite on pH and 4-nitrophenol structure in solution is estimated. It is shown that glauconite increases pH of aqueous environment to 8 and shifts the equilibrium towards the formation of aci-form 4-NF. The conditions of sorption 4-NF by glauconite are established: the sorption time 20 min, the mass of the sorbent (0.50–1.0) g. The isotherm of sorption by 4-NF glauconite has been obtained; its interpretation is given using the Langmuir and Freundlich equations. The main quantitative sorption characteristics of glauconite such as recovery (R = 64%), distribution coefficient (D = 88) and the Langmuir and Freundlich constants for 4-nitrophenol are calculated. These experiments indicate the potential use of the glauconite from Beloozersk deposits (Saratov region) for 4-NP from various waters.
