Kinetics and Cooling Temperature Effect of the Transfer of Soluble Organic Compounds from Heat-Modified Polystyrene Into Saliva and Sweat (original) (raw)

2014

Abstract

In this study attempt was made to produce useful items from disposed polystyrene by modification with heat. Heat-modified polystyrene obtained by cooling the polymer melt at 285K, 303 K, 313K, 353K, 373K and 423K, were subjected to analysis to determine their ability to transfer some of their organic composition into saliva and sweat. The extents of material transfer and kinetics of the transfer process were determined. The research revealed that polystyrene waste can be recycled by heat application into useful products. And the products can transfer some of its material (organic) composition into saliva and sweat at 37 oC. It was observed that more materials are transferred into saliva than in sweat, and at equilibrium, the difference in the amount of materials transferred is 13.16%. Bio-dissolved compounds from the heat-modified polystyrene in the body fluids increased with increase in cooling temperature. In addition, the transfer of materials from the heat-modified polymer into ...
