Scope

Scope: This document describes a method for determining the silicon content in polyethylene and polypropylene using inductively coupled plasma emission spectrometry. This document is applicable to the determination of silicon content in polyethylene and polypropylene (including powders, granules, films, and pipes of polyethylene and polypropylene), with a detection limit of 0.3 mg/kg for silicon elements. Main technical content: After the sample is ashed in a muffle furnace, the resulting ash is mixed with lithium tetraborate and melted at high temperature. The melted sample is dissolved with tartaric acid and hydrochloric acid, diluted with water to a specified volume, and then introduced into an inductively coupled plasma emission spectrometer for measurement. By comparing the emission intensity of the sample solution with that of the standard solution at a specific wavelength, the concentration of the measured element in the sample solution can be obtained.
