Abstract
The preparation method of modified chitosan films for adsorption of pyrene from solution is described. Solid-phase luminescence of samples was studied, degree of extraction and index of polarity of microenvironment of pyrene molecules was determined. It has been proven possible to carry out luminescent analysis of substances for pyrene content using made films. The observed results demonstrate an ability for the using method of solid-phase luminescence (SPL) to increase the range of optical transparency and avoid pre-extraction and concentration of the test samples .
Highlights
Nowadays, polycyclic aromatic hydrocarbons (PAH) are one of the most dangerous carcinogens
The results confirm the high solubilizing ability of solid matrices based on chitosan and allow using the hydrophobic properties of chitosan films in hydrophobic form for pyrene analysis
It was found that solid-phase luminescence (SPL) analysis allows increasing the sensitivity of pyrene detection in aqueous media without additional extraction of substances and concentration with organic solvents
Summary
Polycyclic aromatic hydrocarbons (PAH) are one of the most dangerous carcinogens. The reason for PAH formation is pyrolysis of organic substances. It has been proved that PAH can cause carcinogenic and mutagenic effects and are potent immunosuppressants. Effects have been documented on immune system development, humoral immunity and on host resistance. PAH are accumulated in the human body and cause a change in the structure of DNA, which results in cancer. In this regard, the selected topic is relevant in modern environmental conditions for the protection of human health [2,3,4]
