Highly sensitive and selective water-soluble fluorescent probe for the detection of formaldehyde in leather products

Excess formaldehyde (FA) provides a significant threat that causes irreversible damage to both the environment and human health, long-term FA emission from commercial leather products is problem. Therefore, help control content, we propose fluorescence-based method detect selectively using reaction-based probe FAP-1. Water-soluble FAP-1 was simply synthesized through two steps optical properties of towards species relevant making were evaluated. Then number genuine samples analyzed reveal content. Compared with international standards, fluorescence competitive 2,4-dinitrophenylhydrazine (DNPH) HPLC method, superior acetylacetone (ACAC) UV–Vis method. As result its reliability, low-cost, simple synthesis, ease operation reduced measurement time compared standard methods, our exhibits great potential for analysis found in other industrial products.
