Utilization of biomass as a renewable and sustainable resource has attracted much attention
around the world. For the first time, a new and green method has been developed to …

Heavy metal pollution of water has become a global issue and is especially problematic in
some developing countries. Heavy metals are toxic to living organisms, even at very low …

Copper ions are not only physiologically essential for life but also hazardous materials
causing a series of neurodegenerative diseases. Photoelectrochemical (PEC) detection has …

A new solid phase extractor, nano-scale diboron trioxide/titanium dioxide composite
material, was synthesized and used for separation and/or preconcentration of trace …

An enrichment-separation procedure based on the coprecipitation of gold (III), palladium (II)
and lead (II) ions with nickel (II)-5-methyl-4-(2-thiazolylazo) resorcinol complex has been …

A method of separation and preconcentration of cadmium, cobalt, copper, nickel, lead, and
zinc at trace level using activated carbon is proposed. Activated carbon with the adsorbed …

A novel electrochemical sensor was developed for the sensitive and selective detection of
Cu 2+, Pb 2+ and Cd 2+, which was based on NH 2-MIL-88 (Fe)-rGO composite modified …

In this research, for the first time, fluorescent carbon quantum dots (CQDs) synthesized by
using a green, simple, and efficient one-step hydrothermal carbonization technique from …

Electrochemical methods and devices have ignited prodigious interest for sensing and
monitoring. The greatest challenge for science is far from meeting the expectations of …

It is of great significance to accurately and reliably detect trace lead (II)(Pb2+) ions,
preferably at sub-nM level due to the possible long-term accumulation of Pb2+ in the human …
