“…Many researchers have demonstrated empirical approaches adopted to remove or control specific pesticides or their combinations, such as ozonation with other oxidative processes, such as active carbon, UV radiation 23 , gamma radiation-based photolysis 24 , electrochemical treatment processes, combined UV Fenton processes 25 , oxidative degradation 26 , and nanomaterials 27 . In addition to employing activated biomass, modified magnetic activated biomass or nanocomposites have also been shown to be effective at removing organic toxicants as well as other elements, such as aluminum, uranium and others, from aqueous solution due to their reusability and large surface area 28 – 32 . Altintig et al have shown that dyes can also be removed from water samples using modified magnetic activated carbon 33 , 34 .…”

The emerging contaminant chlorpyrifos, an insecticide, is generally used in agricultural fields to control termites, ants, and mosquitoes for the proper growth of feed and food crops. Chlorpyrifos reaches water sources for multiple reasons, and people who use water from nearby sources is exposed to chlorpyrifos. Due to its overuse in modern agriculture, the level of chlorpyrifos in water has drastically grown. The present study aims to address the problem arising from the utilization of chlorpyrifos-contaminated water. Natural bioadsorbents Bael, Cauliflower, Guava leaves Watermelon, and lemon peel were employed to remove chlorpyrifos from contaminated water under specific conditions of various factors, such as initial adsorbate concentration, dose of bioadsorbent, contact time, pH, and temperature. Maximum removal efficiency of 77% was obtained with lemon peel. The maximum adsorption capacity (qe) was 6.37 mg g−1. The kinetic experiments revealed that the pseudo second order model (R2 = 0.997) provided a better explanation of the mechanism of sorption. The isotherm showed that chlorpyrifos adsorbed in lemon peel in a monolayer and was best suited by the Langmuir model (R2 = 0.993). The adsorption process was exothermic and spontaneous, according to thermodynamic data.
