Fluorescence Characteristic of Dissolved Organic Matter Leached from Two Types of Plastic Including LDPE and PP Using Fluorescence Excitation-Emission Matrix (FEEM) Spectroscopy
Keywords:
dissolved organic matter , LDPE, PPAbstract
Background and Objectives : The objective of this research is to study the Fluorescence characteristics of Dissolved Organic Matter, DOM leached from two types of plastics, Low density polyethylene (LDPE) and Polypropylene (PP), by using Fluorescence excitation-emission matrix (FEEM) spectroscopy. It has been found in multiple investigations that DOM leaches from plastic. The carbon cycle and DOM are connected and this topic has not been the focus of any research in Thailand.
Methodology : LDPE and PP plastics were examined for leaching under natural light and temperature for 30 days. The samples were measured with a Spectrofluorometer.
Main Results : Results showed that DOM are leached from LDPE and PP. Fluorescence characteristics of DOM leached from LDPE were similar to those of PP, with peaks appearing at excitation-emission (ex/em) levels of 300/337-339 and 290-300/338-353 nm. The amount of DOM leached from LDPE was less than PP plastic. The highest amount of DOM was found on day 1 of the experiment and decreased gradually.
Conclusions : DOM are leached from both LDPE and PP plastic. There was no difference between DOM characteristic of LDPE and PP. However, the amount of leached DOM from LDPE was less than PP plastic.
