Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO

member bodies). The work of preparing International Standards is normally carried out through ISO technical

committees. Each member body interested in a subject for which a technical committee has been established has

the right to be represented on that committee. International organizations, governmental and non-governmental, in

liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical

Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.

Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.

Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this part of ISO 14869 may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

International Standard ISO 14869-1 was prepared by Technical Committee ISO/TC 190, Soil quality, Subcommittee

SC 3, Chemical methods and soil characteristics.

ISO 14869 consists of the following parts, under the general title Soil quality —Dissolution for the determination of

total element content:

Part 1: Dissolution with hydrofluoric and perchloric acids

Part 2: Dissolution by alkaline fusion

摘要：

ISO 14869-1-2001 是一项国际标准，规定了用于土壤和类似环境样品中元素测定的溶解方法，特别针对利用氢氟酸和过氯酸进行样品完全消解的前处理流程。该标准适用于原子吸收光谱法、电感耦合等离子体发射光谱法等后期仪器分析，为环境监测、农业研究和地质调查提供可靠、可重复的样品制备指南。掌握 ISO 14869-1-2001 对于确保土壤重金属等元素分析结果的准确性与合规性至关重要。
