REMOVAL OF DYES FROM SYNTHETIC WASTEWATERS USING BIOSYNTHESIZED SILVER NANO PARTICLES

The present experiment was carried out using agno3 nano particles for dye decolorization using pterocarpus santilanus leaves by bio synthesis process. The variables effecting the decolorization process are contact time, pH, concentration, dosage and temperature. The characterization studies were carried out using ftir and xrd. The dyes experimented in the present study are methyl orange (mo), phenol red (pr), safarian stain powder (ssp) and bromo cresol green (bcg). The optimum pH for pr-5, mo-4, ssp-3 and for bcg-6 were found. The positive results confirmed that pterocarpus santilanus leaves broth combined with silver dioxide solution formed silver nano particles and it is capable of removing dyes.
