Protein-like substances and humic substances are the main components of natural organic matter (NOM) produced by biochemical reactions after disinfection of Zooplankton. To eliminate interference in fluorescence detection of organic matter in natural water, a clustered flower-like AlOOH sorbent was prepared. The sorbent can selectively adsorb humic acid (HA) from mixed solutions and restore the fluorescence properties of tryptophan and tyrosine. A stepwise fluorescence detection strategy was developed and successfully applied to natural water with Zooplankton Cyclops to overcome fluorescence quenching interference.
Protein-like substances produced by biochemical reactions after disinfection of Zooplankton like Cyclops and humic substances in natural water are the main components of NOM (Natural organic matter). To eliminate early warning interference in the fluorescence detection of organic matter in natural water, a clustered flower-like AlOOH (aluminum oxide hydroxide) sorbent was prepared. HA (humic acid) and amino acids were selected as mimics of humic substances and protein-like substances in natural water. The results demonstrate that the adsorbent can selectively adsorb HA from the simulated mixed solution and restore the fluorescence properties of tryptophan and tyrosine. Based on these results, a stepwise fluorescence detection strategy was developed and used in natural water rich in zooplanktonic Cyclops. The results show that the established stepwise fluorescence strategy can well overcome the interference caused by fluorescence quenching. The sorbent was also used for water quality control to enhance coagulation treatment. Finally, trial runs of the water plant demonstrated its effectiveness and suggested a potential control method for early warning and monitoring of water quality.
