Attached β-cyclodextrin/γ-(2,3-epoxypropoxy) propyl trimethoxysilane to graphene oxide and its application in copper removal

The environmental applications of graphene oxide and β-cyclodextrin (β-CD) have attracted great attention since their first discovery. Novel nanocomposites were successfully prepared by using an esterification reaction between β-cyclodextrin/γ-(2,3-epoxypropoxy) propyl trimethoxysilane grafted graphene oxide (β-CD/GPTMS/GO). The β-CD/GPTMS/GO nanocomposites were used to remove the Cu2+ from ...

Evaluation of contaminants in fluorosilicic acid used for public water fluoridation in the Santos region, Brazil

Fluorosilicic acid is one of the main products used in water fluoridation. As a by-product of the phosphate fertilizer industry, it may contain contaminants that are harmful to human health. The ...

Circular Dichroism Spectrometer

The Circular Dichroism Spectrometer MOS-500 uses an innovative and patented three stage wavelength selection system to bypass the limitation of traditional prism-based monochromators. The design delivers outstanding performance in wavelength range, sensitivity, precision, speed, and modularity.Operating cost is reduced as well, since the MOS-500 requires purging of optics only when working below ...
