EFFICIENT REMOVAL METHYLENE BLUE DYE AND LEAD ION USING A HYBRID ORGANIC-INORGANIC HYDROGEL

The aim of this work is to study the feasibility of sodium alginate-g-acrylic acid/SiO2hydrogel nanocomposite towards its potential application as high performance adsorbent for removalof Methylene Blue (MB) dye and Pb2+ from aqueous solution. In this regard, the effects of agitationtime, pH, initial dye concentration, adsorbent dose, silicone dioxide concentration, monomerconcentration and temperature were optimized with respect to dye and ion adsorption capacity ofhydrogel nanocomposites in detail. In general, the results indicated that the synthesized hydrogelnanocomposite with biodegradability and biocompability properties can be used in wastewatertreatment via dye and heavy metal adsorption.
