Data from the batch adsorption of ciprofloxacin and lamivudine from synthetic solution using jamun seed (Syzygium cumini) biochar: Response surface methodology (RSM) optimization.

This dataset expresses the experimental data on the batch adsorption of ciprofloxacin and lamivudine from synthetic solution using jamun seed (JS) (Syzygium cumini) biochar. Independent variables including concentration of pollutants (10-500 ppm), contact time (30-300 min), adsorbent dosage (1-1000 mg), pH (1-14) and adsorbent calcination temperature (250,300, 600 and 750 °C) were studied and optimized using Response Surface Methodology (RSM). Empirical models were developed to predict the maximum removal efficiency of ciprofloxacin and lamivudine, and the results were compared with the experimental data. The removal of polutants was more influenced by concentration, followed by adsorbent dosagage, pH, and contact time and the maximum removal reached 90%.

Evaluation of potentiality of traditional hygienic practices for the mitigation of the 2019-2020 Corona Pandemic.

The coronavirus outbreak threatens global well-being, costing thousands of lives and an unstable economy. Traditional hand-washing (HaWa) with clean water and hand-washing sanitizers (HaWaSas) are among WHO recommended practices against the outbreaks. HaWaSa and HaWa lacked proper quality monitoring evaluation that may pose health risks. The current study investigates the potential of traditional hygienic practices adopted to mitigate the 2019-2020 Pandemic. It involved assessing the effectiveness of 15 HaWaSa collected from the Dodoma market. Thirty volunteered participants were subjected to different hygienic practices involving HaWa and HaWaSa. The obtained hand-swabbed samples were subjected to the streak plate technique for inoculation, followed by counting colonies. The results revealed that, among the collected HaWaSa brands, only 33.3% were certified by the Tanzania Bureau of Standards (TBS). In the setting under no hand-wash, each client had a different number of colony counts. HaWa did not eliminate all colonies since water acted as a secondary source while only one sanitizer proved effective. The p-values obtained in either setting were greater than 0.05, indicating that each variable was independent. Despite global awareness and fighting against the Coronavirus Disease 2019 (Covid-19) outbreak, quality monitoring of all diagnostic tools, preventive HaWaSa, and related drugs should be prioritized for human safeguard.
