Sorption of diclofenac from aqueous solution using organo-smectites
Original language description
The widespread use of various pharmaceutical and drug compounds around the world is leading to serious environmental pollution of water resources. The objective of this work is design and preparation of different organo-smectites and the assessment of their ability for the removal of analgesics from aqueous solutions. The smectitic clays like montmorillonite (MMT), hectorite (HEC), beidellite (BEI) and nontronite (NAU) were used in both unmodified and cetylpyridinium bromide (CP) modified form as potential sorbent for diclofenac (DC). X-ray diffraction confirmed the intercalation of organic substance into interlayer by calculating the values of the basal spacing. Thermal analysis exhibited, that organic modification generally caused changes of the temperatures of dehydratation, dehydroxylation and total melting processes during heat treatment. Sorption experiments demonstrated excellent ability for DC removal up to 90 % for all smectites.
