Decontamination of tetraconazole underneath direct daylight using Fe doped TiO2 nanoparticles (FeTiO2) as catalyst. FeTiO2 nanoparticles are synthesized and characterised via scanning electron microscopy (SEM) blended with electricity Dispersive X-ray analysis (EDX) and FT-IR. The photocatalytic studies were conducted via the 1 litre of milli-Q water, pH 4.0, 7.0 and 9.0 buffer have been fortified with 1 mL of 1000 mg/L stock solution of tetraconazole 100 g/L EC to get 1 μg/mL awareness of pesticide animated in water. Three sets of such samples in triplicates were organized and sonicated for 10 minutes to get homogeneous concentration of pesticide active in water and categorized as S1, S2, and S3. Two units of samples (S1 and S2) have been introduced FeTiO2 nanoparticles to get 0.06 g/L content material of photocatalyst. S1 and S3 units of samples were exposed to solar light. S2 set of samples have been kept in an oven at 40°C in dark. The milli-Q water spiked with stock answer of pesticide and without addition of FeTiO2 nanoparticles (S3) were also exposed to sun mild for the size of photolytic degradation of pesticide in water. The FeTiO2 added milli-Q water without spiking of pesticides (S4) was additionally maintained as untreated control for the identification of absence of pesticide. The amassed samples had been quantified using a validated HPLC-UV approach. Kinetic parameters including rate constant (k), DT50 and DT90 had been calculated the use of the dissipation details of tetraconazole.
