Pollution caused by heavy metal ions is becoming an increasingly critical problem every
year. Heavy metal ions such as arsenic, cadmium, chromium, lead, and mercury are very …

Heavy metal pollution has gained global attention due to its high toxicity and non-
biodegradability, even at a low level of exposure. Therefore, the development of a …

A mercury ion imprinted polymer material was prepared using a thiourea derivative
functionalised graphene quantum dot (GQDTU) as the functional monomer using …

From an environmental perspective, there is interest in using agroindustrial waste not only in
transforming it into activated carbon for adsorption applications, but also in exploring its use …

Due to the considerable risks of heavy metal to the humans' health, it is very necessary to
provide an efficient determination technique. The present research procured a modified …

Coffee industry produces more than eight million tons of waste coffee grounds (WCG)
annually. These WCG contain caffeine, tannins, and polyphenols and can be of great …

The molecular dynamics and density functional theory (DFT) can be applied to discriminate
electrocatalyst's electron transfer (ET) properties. It will be interesting to discriminate the ET …

One of the household methods most used to prepare the coffee beverage is the coffee
dripping method, which generates millions of tons of coffee waste (CW). Its disposition …

The diverse composition of biomass waste, with its varied chemical compounds of origin,
holds substantial potential in developing low-cost carbon-based materials for …

Herein, we reported carbon paste electrode modified with graphitic carbon nitride (g–C 3 N
