ABSTRACT The present work investigates the intensification of biological oxidation ciprofloxacin‐based synthetic effluent using acoustic cavitation‐based pretreatment techniques. Cow‐dung based sludge acclimatized with was used for experiments at a 1:3 to loading treatment time 48 h. Conventional resulted in 48.79% CIP degradation, which demonstrated be enhanced through pretreatment. optimized conditions cavitation were 125 W power and 70% duty cycle, optimum oxidant loadings combination studies 150 mg/L H 2 O , potassium persulfate (KPS), 200 mg/h 3 . degradation after application 63.27%, 79.23%, 68.27%, 82.27% AC, AC + KPS, pretreated effluents, respectively. Toxicity analysis against test organisms Pseudomonas aeruginosa ( P. aeruginosa) Saccharomyces cerevisiae agar well diffusion method confirmed that reduced toxicity leading biodegradation. Overall, current elucidated efficiency combined KPS effective ciprofloxacin.

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
