Abstract

Detection of E. coli bacteria in water samples can indicate the presence of other bacterial contamination in feces. Bacterial contamination can be treated with antibiotics, but excessive use of antibiotics leads to the emergence of multiresistant bacteria. Therefore, alternative antibacterial agents must be explored. Copper ion/zeolite composite has been widely studied as an antibacterial agent. However, the released copper ions accumulate in water and are toxic to humans; this can be prevented by converting copper ions into copper oxides (CuO and Cu2O). In this study, copper oxide/zeolite composite is synthesized and characterized using the heating method, followed by evaluation of its effect, antibacterial activity, and potential application as a water filter. The results showed that heat treatment and combination of zeolite with copper did not change the composition of zeolite, rather impurities were reduced from natural zeolites. Antibacterial activity test against E. coli showed that the copper oxide/zeolite composite possessed good antibacterial activity and exhibited better potential as a water filter compared with copper/zeolite. The copper ion released from the synthesized materials was under 2 mg/L, indicating that it is safe for use provided the minimum contact between the sample and water for less than 20 min or 50–60 min.

Abstract

Water pollution has become a major global concern owing to its complexity and widespread impact. Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) are the most common bacterial contaminants in water sources, which pose significant threats to public health. To mitigate water contamination by these pathogenic microorganisms, developing and implementing effective water treatment technologies are essential. A promising approach involves using antibacterial water filtration systems. Herein, zinc oxide (ZnO) nanoparticles were synthesized via hydrothermal and precipitation methods as antibacterial agents for water treatment. These preparation methods required considerably low synthesis time. A capping agent was used to control nanoparticle growth and produce small nanoparticles. The synthesized ZnO nanoparticles were added in the surface of geopolymers to obtain ZnO/geopolymer composite granules, which improved their suitability for water filtration. The antibacterial activity of the ZnO nanoparticles and their composite granules was evaluated. Results indicated that synthetic ZnO exhibited superior antibacterial performance than commercial ZnO against S. aureus (gram-positive) and E. coli (gram-negative). Furthermore, incorporating either commercial or synthetic ZnO into the geopolymer matrix moderately enhanced the antibacterial activity of the resulting material. Notably, the addition of as low as 5 wt.% ZnO was sufficient to significantly improve the antibacterial efficacy of the composite. This finding highlights the potential of ZnO in water treatment applications.
