ASTM D2929-89(2019)e1 用X射线荧光法测定纤维素材料硫含量的标准试验方法

1.1 This test method covers determination of sulfur content of cellulosic materials by X-ray fluorescence. 1.2 Using appropriate standards, the range of the procedure is from approximately 10 ppm to 20 % sulfur. 1.3 This test method is proposed specifically as an alternative to Test Methods D871, sections on Significance and Use, Apparatus, Reagents, Procedure and Calculation of Hydroxyl Content, and Test Methods D817, sections on Summary of Test Method, Significance and Use, Apparatus, Reagents, and Procedure of Hydroxyl Content. As applied to cellulose esters it measures the combined sulfur and sulfur in the accompanying inorganic salts. 1.4 To determine combined sulfur, the sample, when soluble, must first be reprecipitated into dilute acid to remove the noncombined sulfur compounds. 1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For a specific hazard statement, see 7.2.1. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Sulfur Content of Cellulosic Materials by X-Ray Fluorescence

ISO 12830:2019 纸浆和纤维素纳米材料.酸溶性镁钙锰铁铜钠钾的测定

This document specifies the procedure for the determination of acid-soluble magnesium, calcium, manganese, iron, copper, sodium and potassium by atomic absorption spectrometry (AAS) or by inductively coupled plasma emission spectrometry (ICP/ES). The acid-soluble element comprises the acid-soluble part of the incineration residue, i.e. that part of the ignition residue obtained after incineration which is soluble in hydrochloric acid or nitric acid. In cases where the residue is completely soluble, the result obtained by the procedure specified in this document is a measure of the total amount of each element in the sample. This document is applicable to all types of paper, board, pulps and cellulose nanomaterials. The limit of determination depends on the element and on the instrument used.

ISO 1762:2019 纸、纸板、纸浆和纤维素纳米材料.在525℃下燃烧时残渣（灰分含量）的测定；C

This document describes the determination of the residue (ash content) on ignition of paper, board, pulps and cellulose nanomaterials at 525 °C. It is applicable to all types of paper, board, pulp and cellulose nanomaterial samples. This document provides measurement procedures to obtain a measurement precision of 0,01 % or better for residue (ash content) on ignition at 525 °C. Determination of residue (ash content) on ignition at 900 °C of paper, board, pulps and cellulose nanomaterials is described in ISO 2144. In the context of this document, the term “cellulose nanomaterial” refers specifically to cellulose nano- object (see 3.2 to 3.4). Owing to their nanoscale dimensions, these cellulose nano-objects can have intrinsic properties, behaviours or functionalities that are distinct from those associated with paper, board and pulps.

BS ISO 21400:2018 纸浆 纤维素纳米晶硫及硫酸半酯含量的测定

What is this standard about? This document specifies procedures for the laboratory determination of the total elemental sulfur and the sulfate half-ester content of cellulose nanocrystals (CNCs) by inductively coupled plasma-optical emission spectroscopy and conductometric titration, respectively, including sample preparation, measurement methods and data analysis. This document is applicable to the characterization of CNCs: a) with all monovalent counterions (particularly hydronium and sodium cations); b) which are either in the never-dried state in aqueous suspension, or have been redispersed from a dried form; and c) which have been extracted from any naturally occurring cellulose source using a range of sulfuric acid hydrolysis conditions, or have been sulfated post-hydrolysis using sulfuric acid.
