Abstract Materials haven't currently been prevented in existing regulations for the water quality areas are considered as emerging pollutants. Organophosphorus insecticides and pharmaceutical residues are two groups of emerging pollutants having devastating impact on environment and water systems. In this study, the authors efficiently created the hydrochar (biowaste banana peels source) burdened with titanium nanoparticles (HC-TiNPs) via a microwave-Ultrasonic assisted (an efficient green as ecofriendly environment technique) hydrothermal method. Such created material was branded and evaluated for removing harmfully significant pesticides e.g., Diazinon (DIA), Terbufos (TER) and Ethoprophos (ETH), combined with four pharmaceutical compounds e.g., Paracetamol (PAR), Ketoprofen (KET), Diclofenac (DIC) and Ibuprofen (IBU) from aqueous solutions. DFT study be computed the stability of MOF and its powerful to absorb the chemical residues. It indicated the opti­mized structures outlined the strong adsorption due to negative charge trans­fer from MOF to the insecticide or pharmaceutical pollutants. The surface textural and morphological structures of as-obtained composite were determined using different analytical tools. The influence of various parameters, including adsorbent dosage (35-75 mg), initial concentration (0.1-1.2 mg/L), incubation time (25-55 min) and pH (4-8) can be determined for both insecticide and pharmaceutical. Under these conditions, HC-TiNPs was efficiently used to remove insecticide and pharmaceuticals from ecological water samples.
