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 ...
Vortex-assisted surfactant-enhanced-emulsification liquid–liquid microextraction with solidification of floating organic droplet combined with flame atomic absorption spectrometry for the fast determination of cadmium in water samples
New CRM for trace elements in chocolate released (ERM-BD512)
On 1 January 2018 a new amendment ((EC) No 488/2014) to Commission regulation (EC) No 1881/2006 came into force establishing, among others, new maximum residue levels (MRLs) for cadmium in chocolate and cocoa products. To support monitoring of ...

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 ...
