New Aluminum Silicates Findings Has Been Reported by Y.M. Lin et al

June 13, 2014

By a News Reporter-Staff News Editor at Science Letter -- Current study results on Aluminum Silicates have been published. According to news reporting originating from Mawson Lakes, Australia, by NewsRx correspondents, research stated, "In this study, bentonite (Bent)-supported nanoscale zero-valent iron (Fe-0) (Fe(0)Bent) was prepared to remove acid violet red B from an aqueous solution. Scanning electron microscopy (SEM) images of Fe Bent and batch experiments indicated that the presence of bentonite decreased aggregation of iron nanoparticles and increased their reactivity."

Our news editors obtained a quote from the research, "After reacting for 9 min, Fe(0)Bent removed 95.6% of acid violet red B with a concentration of 800 mg/I compared to Fe-0, which removed 75.1%. Iron oxide and hydroxide were the reaction products of the reaction of Fe Bent with acid violet red B. UV-vis spectra showed that the absorption peak of acid violet red B was degraded due to the break of azo linkages. Kinetic studies showed that the degradation rate suited the pseudo-first-order model well. The apparent activation energy was 40.86 kJ/mol, which is typical of a chemically controlled reaction on the smectite surface."

According to the news editors, the research concluded: "The Fe Bent used to remove acid violet red B has the potential to be used for in situ remediation."
