Bamboo and coffee are natural sources of cellulose, hemicellulose, and lignin, making them promising green materials for industrial dye removal. The effects of various adsorption conditions, such as contact time, temperature, dose of bamboo powder (BP), coffee ground (CG), initial concentration of RB, and pH values of RB solution, were measured. Consequently, the kinetics of RB adsorption onto bamboo and coffee was in accordance with the pseudo-second-order model, with an activation energy of 29.51 kJ·mol− 1 for bamboo and 27.46 kJ·mol− 1 for coffee. The Langmuir model is well fitted to the whole adsorption period at different temperatures, indicating maximum adsorption capacities of 6.76, 6.96, and 7.64 mg⋅g− 1 (BP) as well as 6.53, 6.80, and 7.51 mg⋅g− 1 (CG) at 30°C, 40°C, and 50°C, respectively. Moreover, the spontaneous nature of the a...

Hence, in order to prevent an increasing infectious disease risk, current management strategies against COVID-19 should strictly comply for stopping-up the spread of COVID-19 outbreak. There is a major challenge in the timely diagnosis (by kits, etc.) to prevent COVID-19 infection outbreak until proper drugs or vaccines for treating COVID-19 patients are introduced. Therefore, it is essential to demand personal protective manners for each person in against of COVID-19 infection. In this article, the symptoms of COVID-19 and the effect of handwashing in against of COVID-19 are mentioned, as well as its benefits in the COVID-19 infection prevention are understood more clearly.
