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.

Portable X-ray Fluorescence Spectrometry for the analyses of Cultural Heritage

IOP Conference Series: Materials Science and Engineering, 2012
Field Portable Energy Dispersive X Ray Fluorescence (FP-EDXRF) is particularly useful to analyze works of art, mainly because of his noninvasive and multielemental capability. In many situations FP-EDXRF is the only non invasive technique that can be realistically used to gain some information about the chemical composition of precious and unique ...
