| 摘 要： | 以聚四氟乙烯(PTFE)悬浮体为化学改进剂,采用原位分离基体电热蒸发电感耦合等离子体原子发射光谱法(ETV-ICP-AES)测定了二氧化锆中痕量杂质Fe,Al和Ni.考察了灰化温度、灰化时间、蒸发温度、基体浓度等因素对待测物信号强度的影响.在优化实验条件下,方法的检出限为4.2ng·mL-1(Al)～11ng·mL-1(Fe),相对标准偏差为3.1%(Al)～4.9%(Ni).

| Abstract: | A novel method for the analysis of ZrO2 powder via in-situ separation of the matrix from the analytes is described, based on the use of a polytetrafluorethylene (PTFE) emulsion as a chemical modifier. The main affecting factors, including the flow rate of carrier gas and auxiliary carrier gas, ashing temperature and time, matrix concentration, signal record time, and vaporization temperature and time, were investigated systematically. Under the optimum operating conditions, the detection limits (DL) of analytes vary from 4.2 ng x mL(-1) (Al) to 11 ng x mL(-1)(Fe). The relative standard deviations (RSDs) are 3.1%-4.9%. |
