A pectin zirconium (IV) selenotungstophosphate (Pc/ZSWP) nanocomposite was prepared via sol-gel method. The material was characterized using different techniques such as FTIR, SEM and TEM. The adsorptional/photocatalytic activity of Pc/ZSWP was investigated for the removal of methylene blue and malachite green dyes in two different conditions. It was revealed that the synergistic adsorptional/photocatalytic degradation of dyes was more efficient than mere adsorption in dark followed by photocatalysis. The photocatalytic degradation percentage of MB and MG dyes onto Pc/ZSWP nanocomposite was found out to be 89.21 and 79.27% in 3 h of photo irradiation which is higher than for adsorption in dark followed by photocatalysis. The antimicrobial activity of Pc/ZSWP was also ascertained against Escherichia coli.
