The present work aims to reduce the water surface tension using dispersed organophilic clay minerals toincrease the adsorption water pollutants (organic and inorganic) into the clay galleries. Therefore,sodium montmorillonite (Na-MMT) was functionalized with amphphiles based on crosslinked nanogelpolymers of N-isopropylacrylamide (NIPAm), sodium 2-acrylamido-2-methylpropane sulfonate (Na-AMPS), acrylamide (AAm) and acrylamidopropyl)trimethylammonium chloride solution (APTAC) usingsurfactant free technique. The chemical interactions between nanogels and Na-MMT and their chemicalstructure were confirmed by FTIR analysis. The intercalation and exfoliation of Na-MMT were confirmedby wide-angle X-ray diffraction. The morphology of Na-MMT nanogel composites was investigated byTEM analysis. The adsorption capacities of the prepared Na-MMT nanogels for methylene blue dye,cobalt and nickel cations from water were investigated. The data indicated that the Na-MMT nanogelsreduced the surface tension of water and efficiently remove dye and metal ions from water.
