Mentha Arvensis Assisted Synthesis of Silver from Silver Nitrate
We report biosynthesis of silver using crude aqueous extract of Mentha arvensis at room temperature. The use of crude aqueous extract of Mentha arvensis as reducing agent is the first report on the synthesis of silver. XRD study suggests the formation of silver. UV-visible spectrum shows characteristic surface plasmon resonance (SPR) absorption peak of silver at 450 nm. FT-IR has emerged as a major tool to predict involvement of phytochemicals for the reduction of silver nitrate to silver. SEM analysis reveals the morphology of silver crystals and EDX spectrum confirms the formation of silver.
