Abstract :The COVID-19 pandemic has accelerated the need for long-lasting sanitation solutions in households, businesses, and schools. Current disinfectants, like Lysol, kill bacteria and other microbes only at initial application and are ineffective under aqueous conditions. Copper insert ignore into journalissuearticles values(II); ions and Lactic Acid are highly regarded for their synergetic, long-lasting antibacterial properties. Although L-pyroglutamic acid holds similar properties, little research has examined its efficacy with copper metal. The purpose of this experiment is to find a novel, clinically safe, antibacterial solution for instantaneous microbial inhibition and continued inhibition over extended periods of time in aqueous solutions. Two antibacterial solutions utilizing Copper insert ignore into journalissuearticles values(II); Sulfate insert ignore into journalissuearticles values(10 ppm); were developed with 1% Lactic Acid insert ignore into journalissuearticles values(Solution A); and 1% L-Pyroglutamic Acid insert ignore into journalissuearticles values(Solution B);. The extinction rate of Escherichia coli K12 bacteria for each solution and Lysol was recorded. The concentration of E. coli was observed via spectrophotometry at 3-time intervals: Initial Introduction insert ignore into journalissuearticles values(28 Minutes);, Short Term insert ignore into journalissuearticles values(2 Hours); and Long Term insert ignore into journalissuearticles values(72 hours);. At initial introduction, there was no significant difference between solutions insert ignore into journalissuearticles values(p>0.05); ranging from 22 to 28% E. coli loss from the original sample. Significant growth inhibition insert ignore into journalissuearticles values(p <0.05); occurred in Solution A and Solution B compared to Lysol after 2 hours. Solution B sustained higher efficacy compared to Lysol after 72 hours. Overall, our Copper insert ignore into journalissuearticles values(II);/Lactic Acid Solution insert ignore into journalissuearticles values(Solution A); and Copper insert ignore into journalissuearticles values(II);/L-Pyroglutamic Acid Solution insert ignore into journalissuearticles values(Solution B); showed significant improvement when compared to the efficacy of Lysol in aqueous solutions over longer periods of time. Both solutions are cheap, clinically safe, and long-lasting, making them pragmatic options for the future aqueous household sanitation.
