Uncertainty Evaluation in Determination of Boron and Lead in Plastic by ICP-AES

Abstract

Abstract:The content of toxic trace elements is an important index to measure the quality of plastic products. For a long time, the determination of toxic trace elements is the focus of third party detection and so on. It is very important to evaluate the accuracy of detection. In this paper, a mathematical model of the uncertainty of trace elements based on regression equation, constant volume and weighing weight is established. The results show that the content of Boron and Lead in the plastic samples is (66.3 ± 5.4) mg/kg and (500 ±30) mg/kg, respectively.

Critical Quality Control on Determination of Boron Using ICP-OES with Gravimetric Method

“…These tests require methods that can detect at low concentrations with high precision and accuracy. The determination of boron can be carried out by the method of atomic absorption spectroscopy (AAS) [4]- [6]; UV-Vis spectrophotometer [4], [7], [8]; inductively coupled plasma-optical emission spectrometry (ICP-OES) [4], [9], [10]; inductively coupled plasma mass spectrometry (ICP-MS) [4], [9], [10], inductively coupled plasma atomic emission spectroscopy (ICP-AES) [11], [12] and microwave plasma atomic emission spectrometry (MP-AES) [6].…”
