原子吸收法测定岩石中钾、钠的干扰问题,很少见到较详细的报导,由于实际工作需要,我们对此问题进行了实验研究。实验部分 1.仪器及测定条件:WYX-401型原子吸收分光光度计(沈阳分析仪器厂)。仪器使用条件列于表1. Atomic absorption method to determine the interference of potassium and sodium in rocks is seldom seen in more detail. Due to the need of practical work, we have carried out experimental research on this problem. Experimental part 1. Instruments and determination of conditions: WYX-401 atomic absorption spectrophotometer (Shenyang Analytical Instrument Factory). The instrument conditions are listed in Table 1.
