标准范围

ISO 22036:2008描述了用电感耦合等离子体原子发射光谱法（ICP-AES）测定土壤中34种元素的消化液或提取液中的微量元素。该多元素测定方法适用于根据ISO 11466使用王水、根据ISO 14870使用DTPA或其他弱萃取剂获得的土壤提取物，或使用ISO 14869-1的酸消化法或ISO 14869-2的融合法测定总元素含量的土壤提取物。校准方法的选择取决于萃取剂，并可根据萃取剂浓度进行调整。

ISO 22036:2008 describes the determination of trace elements in digests or extraction solutions from soil by inductively coupled plasma - atomic emission spectrometry (ICP-AES) for 34 elements.This multi-element determination method is applicable to soil extracts obtained with aqua regia in accordance with ISO 11466, with DTPA in accordance with ISO 14870 or other weak extractants, or soil extracts for the determination of total element contents using the acid digestion method of ISO 14869-1 or the fusion method of ISO 14869-2.The choice of calibration method depends on the extractant and can be adapted to the extractant concentration.
