ISO 14388-1:2014 土质. 酸式硫酸盐土壤的酸碱会计程序. 第1部分: 介绍和定义, 符号和缩略语, 取样和试样制备

This part of ISO 14388 provides a general introduction to acid sulfate soils and the approaches that can be used to measure the various components of this special group of soils and their potential to produce acidity. It provides a compilation of the test methods, identification and definitions of the symbols, terms, and acronyms used in this series of ISO 14388. While part of the decision-making process can involve the analysis of prepared wet or dry samples, this part of ISO 14388 specifically outlines the procedures that are involved for preparing and analysing dried samples (see Figure 1). This part of ISO 14388 also provides a procedure for pre-treating acid sulfate soil following sampling, prior to their analysis as dried sample using appropriate methods of test. The procedure includes the handling of samples before delivery to the laboratory, and the drying, grinding, and storage of samples. The standard also provides a procedure for archiving a sample after analysis. This part of ISO 14388 provides an acid-base accounting method to calculate the net acid-producing potential of acid sulfate soil materials by individually assessing the acid-producing capacity due to oxidation of inorganic sulfides, the existing acidity, and the effective acid-consuming capacity using results obtained in ISO 14388-2 and ISO 14388-3.

ISO 14388-2:2014 土质. 酸式硫酸盐土壤的酸碱会计程序. 第2部分: 铬还原性硫(CRS)方法论

This part of ISO 14388 specifies a suite of methods used to determine the net acidity in acid sulfate soils. This part of ISO 14388 specifies a method for measuring chromium reducible sulfur (SCR) by iodimetric titration of distilled hydrogen sulfide trapped as zinc sulfide, following acidic chromous chloride digestion. This method determines inorganic sulfides (e.g. pyrite, marcasite, greigite, mackinawite) and elemental sulfur in acid sulfate soil without interferences from organic sulfur and oxidized forms of sulfur such as sulfate. On a separate test portion of soil, the pH in a 1 mol/l KCl soil suspension (pHKCl) is determined. When pHKCl is < 6,5, titratable actual acidity (TAA) is then determined. Subsequently, potassium chloride extractable sulfur (SKCl), calcium (CaKCl), and magnesium (MgKCl) can also be determined. Where jarosite is identified in the soil (or where pHKCl is < 4,5), net acid-soluble sulfur (SNAS) is determined by the difference between hydrochloric acid extractable sulfur (SHCl) and potassium chloride extractable sulfur. On samples where pHKCl is < 6,5, acid neutralizing capacity is determined by measuring either inorganic carbon (CIN) by combustion furnace, or ANCBT (ANC measured by back-titration of acid remaining following an acid digest).

ISO 14388-3:2014 土质. 酸式硫酸盐土壤的酸碱会计程序. 第3部分: 悬浮的过氧化氢氧化复合酸和硫(SPOCAS)方法

This part of ISO 14388 specifies a suite of methods used to determine net acidity in acid sulfate soils. This part of ISO 14388 specifies a method for the determination of pH in a 1 mol/l potassium chloride soil suspension (pHKCl) and where required, titratable actual acidity (TAA). Following this, potassium chloride extractable sulfur (SKCl), calcium (CaKCl) and magnesium (MgKCl) are determined. On a separate test portion, following digestion with 30 % hydrogen peroxide, peroxide pH (pHOX ), titratable peroxide acidity (TPA) and excess acid neutralizing capacity (ANCE) are determined. Following this, peroxide sulfur (SP), calcium (CaP) and magnesium (MgP) are determined. On samples where jarosite is present, or where pHKCl is < 4,5, residual acid soluble sulfur (SRAS) is determined on the soil residue remaining after peroxide digestion. Titratable sulfidic acidity (TSA), reacted calcium (Ca A), reacted magnesium (Mg A) and peroxide oxidizable sulfur (SPOS) are then determined by difference. For peat samples containing substantial levels of organic sulfur, the SPOCAS suite is generally unsuitable for estimating sulfide content, and the chromium reducible suite of procedures should be used instead.
