T/FJAS 017-2022 Deeply analyzing with hydrochloric acid
Abstract
Scope: This document specifies the technical requirements for deep analysis-grade hydrochloric acid, as well as sampling, testing methods, inspection rules, marking, packaging, transportation, and storage. This document applies to deep analysis-grade hydrochloric acid produced using the graphite furnace synthesis/water absorption process. Hydrochloric acid produced by other processes can be used as a reference. Main technical content: The performance of deep analysis-grade hydrochloric acid should meet the following requirements. Item Indicator Total acidity (calculated as HCl) Mass fraction (%) ≥31.0 Iron (calculated as Fe) Mass fraction (%) ≤0.002 Combustion residue Mass fraction (%) ≤0.05 Free chlorine (calculated as Cl) Mass fraction (%) ≤0.004 Sulfate (calculated as SO42- ) Mass fraction (%) ≤0.002 Fluoride ion (calculated as F- ) /(μg/mL) ≤10 Arsenic Mass fraction (%) ≤0.0001
