Pharmaceutical pollutants in wastewater can be effectively degraded by heterogeneous photocatalytic processes (HPP); under light irradiation, these methods use semiconductor photocatalysts to produce reactive oxygen species (ROS), which oxidize and mineralize organic (OPs) into innocuous byproducts. Reactant transport the photocatalyst surface, reactant adsorption, charge carrier formation separation, redox reactions, product desorption are all part of mechanisms. This review article analyzes compares various approaches used prepare photocatalysts. The composition, morphology, crystallinity, production scale, influence synthesis technique selection. While hydrothermal, microwave-assisted, sonochemical, mechanochemical provide greater variety synthesising diverse with varying compositions, morphologies, surface characteristics, flame hydrolysis is appropriate for large-scale TiO2 Because it regulates photocatalyst's charge, electrolytic solution's pH significant processes. Within a certain range, an increase temperature generally results continuous breakdown efficacy; beyond that, rate decomposition decreases. These findings besides giving researchers broad overview current status HP process we believe will also inform its future applications advancements.

This study focuses on the synthesis and characterization of molecularly imprinted polymer (PPy-MIP) to remove 17β-Estradiol (E2) from aqueous solutions. The MIP was synthesized using a non-covalent procedure, incorporating target compound, E2. To PPy-MIP, mixture 300 μl pyrrole 50 ml distilled water stirred for 30 min. After adding 3 g ferric chloride as an oxidant, solution mixed 2 h stored 48–72 h. capability is compared with non-molecularly (NIP) control. Various factors such pH, contact time, dosage, temperature, concentration were investigated optimize performance PPy-MIP. structure confirmed field emission scanning electron microscopy (FESEM), infrared spectrophotometric spectrum (FTIR), X-ray diffraction (XRD). efficiency PPy-MIP in removing E2 obtained 99.97% at optimum condition; while, NIP achieved removal 69.9%. Adsorption data fitted Langmuir isotherms (R2 0.98) pseudo-second-order kinetics 0.99). selectivity toward similar compounds progesterone cholesterol also examined. understand adsorption process, thermodynamics, kinetics, isotherm studies performed. showed good reproducibility only slight decrease after multiple absorption reabsorption cycles. by followed second-order kinetics. utilized pre-concentrate separate real samples (urine, blood, hospital wastewater, tap water). method shows promise efficient selective
