Modelling and simulation of eco-friendly nano-composite based dispenser for controlled release of agrochemicals

Abstract

Experiment was conducted for development of iron oxide nano-adsorbent based pesticide dispenser for three pesticides viz., Coragen (Chlorantraniliprole), TAFFIN (Spinosad) and Profeno-phas. Among these three, Coragen (Chlorantraniliprole) and TAFFIN (Spinosad) were significantly released there active chemical constituents at different dilutions. Kinetic desorption study conducted for 1-9 h until getting constant UV- absorbance values with respective wave length (300-500 nm) for Coragen (Chlorantraniliprole) insecticide desorption to the different dilutions with the distilled water (Spike 1 to 9) and for absorbance values with respective wave length (300-720 nm) for TAFFIN (Spinosad) insecticide desorption to the different dilutions with the distilled water (Spike 1 to 7). Standard pesticide concentrations was measured for the wavelength with highest absorbance for TAFFIN (500 nm) and Coragen (400 nm). Measured wavelength at highest absorbance (400 and 500 nm) for Coragen (Chlorantraniliprole) and TAFFIN (Spinosad) standards showed highest R2 value of 0.97 and 0.99.
