Environmental problems that came from the human activity have many facets, since pollution of the atmosphere arises from vehicles, industrial emissions while pollution of water could be from organic compounds, pesticides etc. These can cause serious health effects, such as respiratory diseases, including asthma and lung cancer. Hence, in the present work, a kinetic study on the effective adsorption and photo degradation of methylene blue (MB) dye, under ultraviolet A (UVA) irradiation of an alkali activated inorganic polymer (geopolymer) with homogeneously dispersed titanium dioxide (TiO₂) micro-particles is presented. In addition, antimicrobial testing of the alkali activated TiO₂ material was performed showing a bacteriostatic effect.
