“…Our results were consequently more alarming, drawing attention to the increase in pesticide residue with the passing of years, and are definitely a threat to the environment. The current investigation revealed that the fruits contain a significant amount of pesticides, which might be toxic to human beings and under the current scenario of environmental pollution [36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51]. This situation will become more alarming in coming years.…”

“…Moreover, at optimum (27)). At higher concentration of H 2 O 2 , it acts as an · OH radical scavenger and hence, at a higher H 2 O 2 concentration the color removal rate slowed down [33]. The overall mechanism of dye color removal in the presence of Fe 0 and H 2 O 2 including reduction, oxidation and coagulation/sedimentation is shown in figure 9.…”

In the present investigation, Zero valent iron (ZVI) was synthesized using ferrous sulfate and borohydrate in the presence of EDTA and characterized by x-ray Diffraction (XRD), Energydispersive x-ray (EDX) and Scanning electron microscope (SEM) techniques. The prepared ZVI catalytic activity was evaluated by degrading Acid Red 1 (AR1) and Acid Green 25 (AG25) dyes. The process variables such as pH, initial dye concentration, ZVI dose, contact time, hydrogen peroxide (H 2 O 2 ) and temperature were optimized for maximum dye degradation. AG25 removal was 98% at pH 4, ZVI dose 0.2 g l −1 , initial dye concentration 50 mg l −1 , 90 min reaction time and 8 mM H 2 O 2 concentration, whereas pH 2, ZVI dose 0.1 g l −1 , 50 mg l −1 initial dye concentration, 8 mM H 2 O 2 and 90 min were found to be optimum for AR1 maximum degradation of 91.60%. Behnajady-Modirshahla-Ghanbery kinetic model and thermodynamic study revealed the spontaneity and endothermic nature of the process. Results revealed that ZVI has potential to degrade the dyes and could possibly be used for the degradation of dyes in wastewater.

Iron molybdate was prepared via simple solution chemistry method and the photocatalytic degradation of a pesticide (endosulfan) was investigated under visible light irradiation. As-prepared (Fe 2 (MoO 4 ) 3 ) was characterized using scanning electron microscope (SEM), x-ray diffraction (XRD), energy dispersive x-ray spectra (EDX), diffused reflectance spectroscopy (DRS) and Zeta particle sizer techniques. The iron molybdate crystallite size was 36 nm, while grain size was in the range of 160-340 nm. The particles of polymetallic compound were spherical, highly porous and with fluffy texture indicating high surface area. DRS revealed Fe 2 (MoO 4 ) 3 was active under visible region since band gap value calculated was 2.7 eV. Response surface methodology (RSM) was employed for the optimization of photocatalytic activity (PCA) of Fe 2 (MoO 4 ) 3 as a function of catalyst dose, H 2 O 2 dose, solution pH and concentration of endosulfan and up to 77% degradation was achieved at optimum conditions, which was monitored by UV/vis spectroscopy. In response to endosulfan degradation, the chemical oxygen demand (COD) and total organic carbon (TOC) were reduced up to 76% and 67%, respectively. Results revealed that iron molybdate is highly efficient photocatalyst for the degradation of endosulfan under solar light irradiation and could possibly be used for the treatment of endosulfan containing wastewater.
