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 ...
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 ...

The cordless battery-operated LEAKSPY SF6 precisely measures SF6 concentration in air by means of a non dispersive infrared sensor (NDIR sensor) and indicates the value on a graphic display in ppmv. The device allows precise localisation of leaks by searching the highest SF6 concentration. Thanks to the high accuracy and the low detection limit it is possible to carry out integral measurements as ...
