abstract

the nano sized tio2 and zno are the most active photocatalysts.  methylene blue was used as a reference molecule for the photocatalytic degradation. the tio2 and zno can totally remove methylene blue dye. the effect of various process parameters like initial concentration, contact time, dose of catalyst and ph on the extent of removal of dye by photocatalysis in presence of tio2 and zno was studied. the results showed that the percentage of dye removal increases with increase in contact time. the optimum contact time was fixed at 180 minutes for both nanomaterials. the results of this study reveal that the dyes could be removed by semiconducting nanomaterials assisted photocatalytic degradation. the semiconducting materials were analyzed by xrd and sem before and after degradation of methylene blue.

Potential Biosorbent Derived from Calligonum polygonoides for Removal of Methylene Blue Dye from Aqueous Solution

The ash of C. polygonoides (locally called balanza) was collected from Lakki Marwat, Khyber Pakhtunkhwa, Pakistan, and was utilized as biosorbent for methylene blue (MB) removal from aqueous solution. The ash was used as biosorbent without any physical or chemical treatment. The biosorbent was characterized by using various techniques such as Fourier transform infrared spectroscopy (FTIR), ther...

Removal of methylene blue from aqueous solutions using modified clay

Introduction: Discharging of industrial colored wastewaters especially into aqueous environments can cause adverse effects on aquatic life due to their toxic natures. In this study, montmorillonite modified by hexadecyltrimethyl ammonium bromide (HDTMA-Mt) was used for the adsorption of methylene blue (MB). Materials and Methods: The influence of surfactant loading rate, contact time, pH, adso...
