Abstract
Bacterial water pollution is a genuine general wellbeing concern since it causes various maladies. Antimicrobial nanofibers can be integrated by incorporating nanobiocides, for example, silver nanoparticles into nanofibers. Nylon 6 was dissolved in formic acid at a concentration of (25 wt. %) and tough antibacterial (AgNO3/Nylon) nanofibers were produced utilizing electrospinning system. Polymer solution was tested before accomplishing electrospinning process to acquire its surface tension, electric conductivity and viscosity, where every one of those parameters increased relatively with increasing concentration of (AgNO3) additions. SEM and EDX spectra were utilized to focus on the morphology, surface elemental membrane, fibers and porosize diameters. The resulted nanofiber membrane has an average fiber diameter of 139 nm for pure nylon 6 and 247 nm for (1.2 wt. % AgNO3/Nylon). The resultant polymer membrane was then tested for their ability to destroy microorganisms in water; antimicrobial tests showed that the prepared nanofibers have a high bactericidal effect against Escherichia Coli Bacteria with inhibition zone (10 mm) and antibacterial activity (99%). Likewise, these results highlight the potential utilization of these nanofibrous mats as antimicrobial agents.
Highlights
The development of energy-efficient water treatment technology has become an important area of research as it offers a solution to the increasingly limited water supplies available to the world’s growing population and industry [1,2,3]
Antimicrobial nanofibers synthesized by incorporating nanobiocides such as silver nanoparticles into the nanofibers
The synthesis of nanofibers consists of metal nanoparticles is well investigated because of the benefits included with the joining of functional properties of metal nanoparticles with the widely applicable properties of nanofibers [4]
Summary
The development of energy-efficient water treatment technology has become an important area of research as it offers a solution to the increasingly limited water supplies available to the world’s growing population and industry [1,2,3]. The reduction of aldehyde groups from (AgNO3) forms a metallic silver. The formic acid goes about as the solvent for (Nylon 6) and a reducing agent for (AgNO3). At the point when silver nitrate is included into the formic acid solution of (Nylon 6), it is reduced into metallic silver by the aldehyde group in the formic acid molecule. The carbonic acid form that is unsteady and rapidly dissociates into carbon dioxide and water [19] The advantage of this system is the in situ stabilization of silver nanoparticles. Ions are reduced to metallic silver, immediately atoms are aggregated into clusters These clusters have very small size and high surface energy, which leads them to form larger particles. The solution was avoided from light and stirred under room temperature for (3) hrs to insure the complete reduction of (AgNO3)
