The pH value of aqueous solution had a major impact on Ag(I) adsorption. The maximum adsorption capacity of Fe 3 O 4 /GO-NH 2 nanocomposites for Ag(I) was 114.90 mg/g. The adsorption process of Fe 3 O 4 /GO-NH 2 nanocomposites for Ag(I) was well described by the pseudo-second-order kinetics model and the Langmuir isotherm model. Silver oxide can be prepared by combining aqueous solutions of silver nitrate and an alkali hydroxide. This reaction does not afford appreciable amounts of silver hydroxide due to the favorable energetics for the following reaction: 2 AgOH → Ag 2 O + H 2 O (pK = 2.875) Unmodified and functionalized cellulose microspheres were able to remove Ag(I) from aqueous AgNO 3 solution serving as a model for a contaminated water medium. Force measurement with AFM was demonstrated to be a helpful method for studying the surface interaction between cellulose microspheres and water contaminants such as monovalent silver ions. 2010-12-15 At the lowest Ag(I) concentration, the maximum removal rate was obtained, while the adsorption capacity was the minimum.

The high removal rate was inclined to be acquired in the process of water treatment compared with adsorption capacity. So, the MEG-NH 2 nanohybrids are an ideal adsorbent to treat low Ag(I) concentration in aqueous solution.

Decreasing in size to nanometer scale has shown distinct improvement in these inherent properties due to larger surface-to-volume ratio. Ag and Cu nanoparticles are also shown higher surface reactivity, and Owing to the electrosteric repulsion characteristic of PAA, the prepared aqueous Ag ink exhibited a remarkable dispersion stability, which was confirmed by sedimentation test, zeta-potential measurement, and rheological analysis. The surface of Ag NPs in an aqueous environment is oxidized in the presence of oxygen and protons, and silver ions are released as the surface dissolves. Thus, the effective silver ion concentration is maintained in the solution, and the antimicrobial effect will last for a long time [ 5 ].
