Excessive consumption of substances such as food colorants, exposure to doses of metal ions, antibiotic
residues and pesticides residues above maximum tolerance limit have a detrimental effect on human
health. Hence in detecting these harmful substances, the development of sensitive, selective and
convenient analytical tools is an essential step. Graphene and graphene like 2D graphitic carbon nitride
have shown great promise in the development of electrochemical sensors for determining the levels of
these substances in different samples. In this paper, graphene and graphene like 2D graphitic carbon
nitride applications on the determination of various food colorants in foods and drinks such as azo dyes
(tartrazine, allura red, amaranth, carmine and sunset yellow); metal ions contaminants, antibiotic and
pesticide residues in the environment are reviewed.
