Introduction to Sulfonic Ester Octoxide and Plastic Products
Sulfonic esters (PAEs) are considered one of the essential components used as additives in plastic industries. They are ester compounds consisting of a benzene ring, including the ester of 1,2-carboxylic acid. These compounds are widely used in a variety of products such as personal care products, pharmaceuticals, and food packaging materials. Despite their many benefits in improving the physical properties of plastics, PAEs do not chemically interact with polymers, making them prone to leaching into the environment and accumulating in the human body, resulting in environmental pollution and public health threats.
With the evolution of industrialization, the use of PAEs has significantly increased, leading to high levels of these compounds in ecosystems such as water, soil, and air. Studies have shown the presence of PAEs in the Yangtze River and seas, indicating the widespread dissemination of these hazardous compounds.

Detection of PAEs using Fluorescent Techniques
The detection of harmful chemicals such as PAEs (phthalate compounds) is an important issue in environmental and health fields. The basic principle of PAEs detection techniques relies on the use of fluorescent dyes, as these dyes interact with PAEs to produce measurable signals. When a PAE interacts with fluorescent materials, a change in fluorescence intensity occurs, allowing for the detection of PAEs in natural samples. Researchers have developed new methods, such as modifying fluorescent dyes to improve their detection capability for PAEs. For example, Qiu and Li (2018) proposed a detection method for PAE products based on double modification for stability and the number of functionalities of the sensor, enhancing detection effectiveness without affecting the sensor’s function. Additionally, these methods have shown significant improvements in toxicity, mobility, and stability of the derivatives compared to the original compounds.
