“…The degree of mineralization of the Acetamiprid was ascertained by measuring the chemical oxygen demand (COD) according to standard methods (Ensano et al 2017 ). Also, the by-products resulting from decomposition of acetamiprid were analyzed by gas chromatography–mass (GC–MS) (Wang and Shih 2016 ).…”

Contamination of water resources by acetamiprid pesticide is considered one of the main environmental problems. The aim of this study was the optimization of acetamiprid removal from aqueous solutions by TiO2/Fe3O4/SiO2 nanocomposite using the response surface methodology (RSM) with toxicity assessment by Pseudomonas aeruginosa BCRC. To obtain the optimum condition for acetamiprid degradation using RSM and central composite design (CCD). The magnetic TiO2/Fe3O4/SiO2 nanocomposite was synthesized using co-precipitation and sol–gel methods. The surface morphology of the nanocomposite and magnetic properties of the as-synthesized Fe3O4 nanoparticles were characterised by scanning electron microscope and vibrating sample magnetometer, respectively. In this study, toxicity assessment tests have been carried out by determining the activity of dehydrogenase enzyme reducing Resazurin (RR) and colony forming unit (CFU) methods. According to CCD, quadratic optimal model with R2 = 0.99 was used. By analysis of variance, the most effective values of each factor were determined in each experiment. According to the results, the most optimal conditions for removal efficiency of acetamiprid (pH = 7.5, contact time = 65 min, and dose of nanoparticle 550 mg/L) was obtained at 76.55%. Effect concentration (EC50) for RR and CFU test were 1.950 and 2.050 mg/L, respectively. Based on the results obtained from the model, predicted response values showed high congruence with actual response values. And, the model was suitable for the experiment’s design conditions.

“…They reported an increase of 66% in the extent of carbofuran degradation when the Fenton process was combined with ultrasound. Also, Wang et al 76 studied the degradation of diazinon using ultrasonic irradiation facilitated by Fenton process. They reported that 98% degradation of diazinon was achieves by sono-Fenton process which increased by 61% compared with Fenton process.…”

DEGRADASI PESTISIDA DIAZINON DENGAN PROSES FOTOKATALISIS SINAR MATAHARI MENGGUNAKAN KATALIS C,N-CODOPED TiO2. Diazinon merupakan salah satu pestisida organofosfat yang sangat luas penggunaannya di bidang pertanian, namun ia bersifat sangat beracun. Pada penelitian ini diazinon didegradasi secara fotokatalisis menggunakakan katalis C,N-codoped TiO2 yang aktif pada sinar matahari. Beberapa faktor yang mempengaruhi proses degradasi dipelajari seperti massa katalis, pengaruh doping pada titania, pH larutan awal, dan waktu irradiasi. Penambahan katalis C,N-codoped TiO2 mampu meningkatkan persen degradasi diazinon secara siginifikan. Diazinon dengan konsentrasi awal 18 mg/l dan volume 20 ml terdegradasi sebesar 90,75% pada kondisi optimum pH 7, 12 mg katalis C,N-codoped TiO2, selama 300 menit fotokatalisis sinar matahari. Data hasil analisis High Performance Liquid Chromatography (HPLC) menunjukkan bahwa diazinon telah berhasil didegradasi.
