“…For example, corona pseudoviruses were reduced by 99% after 30 minutes of exposure to 1000 ppmv of ozone. On the other hand, micro-ozone bubbles provide better and more efficient wastewater disinfection by the formation of shockwaves and OH radicals in the water, resulting in better and more efficient wastewater disinfection (Jacob et al 2021 ).…”

“…Ozone microbubbles can penetrate wastewater and create local hotspots where intense heat is generated by compressing the gas in the microbubbles, resulting in pyrolytic decomposition and the formation of shockwaves and OH radicals in the water. As a result of this phenomenon, microbial contaminants in wastewater are inactivated, resulting in better and more efficient wastewater disinfection (Jacob et al 2021 ).…”

Due to the prevalence of the COVID-19 outbreak, as well as findings of SARS-CoV-2 RNA in wastewater and the possibility of viral transmission through wastewater, disinfection is required. As a consequence, based on prior investigations, this work initially employed the viral concentration detection technique, followed by the RT-qPCR assay, as the foundation for identifying the SARS-CoV-2 virus in wastewater. After that, the ability and efficacy of chlorine, ozone, and UV disinfection to inactivate the SARS-CoV-2 virus from wastewater were examined. Chlorine disinfection is the most extensively used disinfection technology due to its multiple advantages. With a chlorine dioxide disinfectant dose of 40 mg/L, the SARS-CoV virus is inactivated after 30 min of contact time. On the other hand, ozone is a powerful oxidizer and an effective microbicide that is employed as a disinfectant due to its positive characteristics. After 30 min of exposure to 1000 ppmv ozone, corona pseudoviruses are reduced by 99%. Another common method of disinfection is using ultraviolet radiation, which is usually 253.7 nm suitable for ultraviolet disinfection. At a dose of 1048 mJ/cm 2 , UVC radiation completely inactivates the SARS-CoV-2 virus. Finally, to evaluate disinfection performance and optimize disinfection strategies to prevent the spread of SARS-CoV-2, this study attempted to investigate the ability to remove and compare the effectiveness of each disinfectant to inactive the SARS-CoV-2 virus from wastewater, summarize studies, and provide future solutions due to the limited availability of integrated resources in this field and the spread of the SARS-CoV-2 virus worldwide.

An effective, duplicable, and quick method to determine the purity and formulating form of Cetrimide (CE) have studied and modified utilizing the Reverse Phase High Performance Liquid Chromatography (RP-HPLC). The method was based on the separation of the CE using a reverse phase HPLC Shimadzu LC–20 A, Japan, and Phenomenex C18 column (15 × 4.6mm, 5.0μm). The process was carried out by using the mobile phase ammonium acetate solution 0.1M (AA), methanol (MeOH), and the methyl cyanide in the ratio of (15:60:25 V/V/V), a flow rate of 1.0mL/min, at pH = 3, with 10μL sample loop and the UV - spectrophotometry detector was set at 280nm. However, for the optimum conditions the mobile phase composition, wavelength, pH, and flow rate were studied. The calibration carve has obtained in the range of 10-1000mg/L and the correlation coefficient is 0.9985. The average recovery of the standard drug was 97.56%. The LOD was 5mg/L and LOQ is 16.5mg/L for CE. The process was used successfully to determine the CE in the pharmaceutical forms with the average recovery of 95.61 and 96.02%.
