Fluorescence Behavior of Water‐Soluble Porphyrins Immobilized on LTA Zeolite and Its Chlorogenic Acid Polyphenol Sensing in Coffee Wastewater

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
During coffee bean and cherry washing, contaminants are released into water, making this process a major source of water pollution. Chlorogenic acid can be efficiently detected using hybrid zeolite–porphyrin materials by measuring fluorescence quenching, achieving detection limits lower than current regulatory thresholds.
