No full textEvaluation of Fenton and Ozone Treatment Process for the Degradation of Psychiatric Drugs Carbamazepine (CBZ) and Oxcarbazepine (oxCBZ) in Simulated Waste Water (SWW)
No full textThe current research focuses on the evaluation of two advanced oxidation processes (AOPs) viz. Fenton and ozone treatment for the degradation of recalcitrant antipsychiatrics carbamazepine (CBZ) and oxcarbazepine (oxCBZ) in simulated wastewater. The parameters for Fenton reactions viz. pH, Fenton dosage, contact time and Fe2+/H2O2 were optimized using Response Surface Methodology. The optimum conditions obtained were (pH 2.0, Fenton dosage 1.61 g/dm3, Fe2+/H2O2 0.427 and contact time of 25 minutes) which yields a COD destruction of 92.49%. A pseudo-first order rate constant of 0.6185 min-1 and 0.0676 min-1 was observed for the ozonation of CBZ and oxCBZ respectivel
Ozone treatment of sulfamethoxazole in aqueous matrix and toxicity of its degradation products on Pseudomonas aeruginosa and Enterobacter xiangfangensis species
No full textSulfamethoxazole (SMX) is extensively used antibiotic and residue of SMX has been found in surface and drinking water in ng/L concentration. The advance oxidation process such as ozonation has been proposed for removal of SMX into its possible readily biodegradable intermediates and also limits its impact on the environment. About 20 g/h of ozone dosage used for treatment of sulfamethoxazole (four different concentrations of SMX 10 ppm, 20 ppm, 30 ppm and 40 ppm) resulted in 99 % removal within 60 minutes of ozonation with the leftover of its degradation products. However, the toxicity of degradation products of SMX formed after ozone treatment on soil microorganism (Pseudomonas aeruginosa and Enterobacter xiangfangensis) has not been reported. In the current study toxicity of degradation products using MTT assay has been reported. The study revealed that degradation product of SMX not showing any significant cytotoxic effect on the soil micro-organism compared to pure SMX

No full textObjective The ever-growing number of articles related to full-endoscopic spine surgery published in the last few decades presents a challenge which is perplexing and time-consuming in identifying the current research status. The study aims to identify and analyze the most cited works related to full-endoscopic decompression spine surgery, compare the articles published by different publishers and area, and show the current publication status of full-endoscopic research. Methods Using Bibliometrix, CiteSpace, and VOSviewer, we analyzed the bibliometric data selected from the Web of Science database between 1992 and 2022. Spine has the highest H-index with the most-cited journal in the field of full-endoscopic decompression spine surgery. China ranked as the most productive country, whereas the most cited with high H-index papers came from South Korea. For the author analysis, Yeung AT, Ruetten S, Hoogland T, Ahn Y, Choi G, and Mayer HM were the most impactful authors in the global and local citations. The most productive organization is Wooridul Spine Hospital. Conclusion The bibliometric study showed a growing trend of research on full-endoscopic decompression spine surgery over the past 30 years. It has demonstrated that there is a significant increase in the number of authors, institutions, and internationally collaborated countries. However, the quality of studies is still low, and the lack of high-quality clinical evidence and the trend of general journal submissions has somewhat affected the quality of endoscopy journals in recent years
