Detection of copper ions in an aqueous solution by a dual-peak long period fiber grating functionalized with a polypyrrole–chitosan composite

A dual-peak long period fiber grating (DP-LPFG) sensor functionalized by polypyrrole–chitosan composite was proposed for sensitive detection of Cu 2+ ions in aqueous solution. The nitrogen atom on the polypyrrole ring and the amino group on the chitosan chain in the complex matrix can chelate the Cu...
