Determination of 16 Metal Elements in Hydrogen Fluoride Gas by Inductively Coupled Plasma Atomic Emission Spectrometry
摘 要
基于电子工业对氟化氢气体中金属离子含量的严格要求,以自制的简单的气体吸收装置吸收氟化氢气体,通过吸收前后吸收液的质量变化得到氟化氢的质量,采用附带耐氢氟酸进样系统的电感耦合等离子体原子发射光谱仪(ICP-AES)在最优的仪器工作条件下测定吸收液中的钾、镁、铝、钡、锌、铬、钴、镉、铁、铜、镍、铅、锰、钠、钙和锡等16种金属元素的含量。结果表明:16种金属元素的质量浓度均在一定范围内与其对应的光谱强度呈线性关系,相关系数均大于0.999 0,检出限(3s)为0.10~6.0 μg·L-1,测定值的相对标准偏差(n=11)为0.96%~5.0%。
Abstract
Based on the strict quality requirements in the electronic industry, a method for determination of metal impurities in hydrogen fluoride gas was developed by inductively coupled plasma atomic emission spectrometry (ICP-AES) with a hydrofluoric acid-resistant sampling system. A simple self-made absorption device was designed for absorbing hydrogen fluoride gas, and the mass of absorbed hydrogen fluoride was obtained by the mass changes of absorption solution. The 16 metal elements including potassium, magnesium, aluminum, barium, zinc, chromium, cobalt, cadmium, iron, copper, nickel, lead, manganese, sodium, calcium and tin were determined under the optimal instrumental conditions. As found by results that linear relationships between mass concentrations of 16 metal elements and their corresponding spectral intensities were all in the definite ranges, with correlation coefficients greater than 0.999 0. The detection limits (3s) were ranged from 0.10-6.0 μg·L-1, and RSDs (n=11) of the measured values were in the range of 0.96%-5.0%.
