Preparation and Antibacterial Ability of Silver-Loaded Maifanite

Abstract

Silver-loaded maifanite prepared at different particle sizes (60 mesh~200 mesh) and light calcining temperatures (100°C~800°C) of maifanite, different AgNO3solution concentrations (0.025 mol•L-1~0.300 mol•L-1) and pH values (2~7) were researched, simultaneously antibacterial ability of silver-loaded maifanite was investigated. Results indicate that the appropriate conditions of preparing silver-loaded maifanite are that particle size is 200 mesh, light calcining temperature is 100°C, AgNO3concentration is 0.1 mol•L-1at pH=7, and then the silver-loading amount of maifanite gained at this conditions is 1.27wt%; antimicrobial ability of silver-loaded maifanite decreases with increase of light calcining temperature.

Investigation on the adsorption of phosphorus in all fractions from sediment by modified maifanite

“…The result was in accordance with that of Yang et al . (2011), who reported that the main mineral diffraction peak position of maifanite did not change after calcining at 500 °C 45 . On the other hand, some peaks were disappeared and weakened a little after the modification treatment, which might be caused by the decrease of impurity after the modification treatment.…”
