Preparation of a Novel Nano or Submicron Tourmaline Ceramic and its Ability to Inhibit the Activity of the Sulfate-Reducing Bacterium
In this study,novel nano- or submicron-scale tourmaline bacteriostatic ceramics in which nano or submicron tourmaline is one of the central materials,together with nano-zinc oxide,are prepared using ion exchange and solid-phase synthesis techniques.The material is then examined with IR,XRD and XPS and is tested for the ability to inhibit the activity of the sulfate-reducing bacterium (SRB).The calcination temperature of the ceramic is 600 ℃,and the main components are present at 11.17% for Si2p,3.12% for Mo3d,3.47% for Zn2p3,2.86% for Mn2p and 2.35% for Cu2p.Additionally,the density of this material is 1.4-3.5 g/cm3,and its compressive strength exceeds 5.2 MPa,meeting the requirements of ceramic standards.Consequently,the bacteriostatic ceramic inhibits the activity of the sulfate-reducing bacterium effectively without inhibiting the removal of COD and N03-.These results indicate that the sulfate-reducing bacterium maintains its functional metabolism,apart from its sulfate reduction potential,when using this bacteriostatic ceramic,thus achieving the goal of inhibiting the action of the sulfate-reducing bacterium.
