中文摘要: 采用干扰系数模型和电感耦合等离子体原子发射光谱法(ICP-AES)相结合的方式,建立了镍基合金中铈含量的测试方法。选用5~10 mL盐酸和1 mL硝酸低温溶解样品,在仪器射频功率为1125 w、冷却气流量为13 L/min、雾化器气体流量为0.95 L/min和垂直观测高度为13mm的条件下,选取受酸和共存元素干扰形式简单、干扰程度相对较轻的404.076 nm、413.765 nm和456.236 nm作为铈的分析线,并通过干扰系数法校正共存元素对铈的光谱干扰,实现了ICP-AES快速、准确测定镍基合金中铈元素。干扰实验结果表明:分析线404.076 nm受Co、V和Mn干扰,分析线413.765 nm受W、Nb、Co、Ti和V干扰,分析线456.236 nm受Ti、Zr、Nb、Co、Mn干扰。考虑到镍基合金中V、Mn、Zr常为杂质掺入,为了有效简化运算过程,采用干扰系数法执行干扰校正时,主要是校正或消除Co(404.076 nm)、W和Nb(413.765 nm)、Ti和Co(456.236 nm)的干扰。通过对镍基合金GH4099和GH4133B进行分析,经干扰系数法校正后其测定结果与认可值相一致,RSD<8.0 %(n=6)。
Abstract:The determination method of cerium in nickel-base alloy by inductively coupled plasma atomic emission spectrometry (ICP-AES) method-interference coefficient model was established. The sample was dissolved in 5~10 mL hydrochloric acid and 1 mL nitric acid. Under the instrument parameters condition of RF power 1125 w, coolant gas flow 13 L/min, nebulizer gas flow 0.95 L/min and radial view height 13 mm, the spectral lines of 404.076 nm, 413.765 nm and 456.236 nm, which has a simple form of interference and a relatively light degree of interference from acids and co-existing elements, were selected as the analytical lines of cerium element. Determining cerium element in nickel-base alloys was more accurate and rapid by ICP-AES method after using interference coefficient method correcting the spectral interference of co-existing elements on cerium. The interference experimental results showed that the spectral line 404.076 nm was affected by Co, V and Mn; the spectral line 413.765 nm was affected by W, Nb, Co, Ti and V; the spectral line 456.236 nm was affected by Ti, Zr, Nb, Co and Mn. Considering that V, Mn and Zr in nickel-base alloys is often added as an impurity, in order to simplify the operation process effectively, the interference coefficient method is mainly used to correct or eliminate the interference of Co (404.076 nm), W and Nb (413.765 nm), Ti and Co (456.236 nm). The determination results in nickel-base alloys GH4099 and GH4133B that were corrected by interference coefficient method were basically consistent with its certified values and RSD<8.0 % (n=6).
