An electrochemical DNA biosensor for trace amounts of mercury ion quantification

In this work we report the development of an electrochemical DNA biosensor with high sensitivity for mercury ion detection. A new matrix based on gold nanoparticles (AuNPs)-glutathione (GSH)/cysteine was investigated. The interaction between DNA oligonucleotides and Hg2+ ions followed by the formation of Thymine–Hg2+–Thymine (T–Hg2+–T) structures was quantified using different electrochemical ...

Pd/RGO modified carbon felt cathode for electro-Fenton removing of EDTA-Ni

Ethylenediaminetetraacetic acid (EDTA) forms stable complexes with toxic metals such as nickel due to its strong chelation. The electro-Fenton (EF) process using a cathode made from palladium ...

Aluminum monitoring for wastewater treatment

Aluminum salts can be used in wastewater treatment as coagulation agent and flocculant. However, because of its toxic effect on fish, it is important to remove aluminum efficiently before the treated water is released into the environment. Metrohm ...
