摘要
采用硝酸–高氯酸–氢氟酸全消解、原子荧光光谱法测定土壤中的总铅,对标准物质GSS–3、GSS–8、GSS–20进行测定,测定值分别为25.6 mg/kg、20.6 mg/kg和13.0 mg/kg,相对标准偏差为2.3%~4.7%,测定值均在标准值范围内,相对标准偏差满足标准要求,结果满意。
With HNO_3-HF-HCLO_4 mixed acids full digestion, atomic fluorescence spectrometry was used to determine total lead in soil. Reference standards including GSS-3,GSS-8 and GSS-20 were determined; the values was 25.6 mg/kg, 20.6 mg/kg and 13.0 mg/kg respectively; the RSD was 2.3%-4.7% within the standard range.
