acid soluble sulphate test

BS EN 1744-1: Clause 12: Acid soluble sulphate — Celtest

2018-10-19  Celtest are UKAS accredited to perform the acid soluble sulphate test in accordance with clause 12 of BS EN 1744-1. The test involves extracting sulphates from a test portion of the aggregate by dilute hydrochloric acid. The sulphate ion content is determined by gravimetry and expressed as a percentage by mass of the aggregate.

Testing for Sulfate ion Qualitative Analysis for SO42-

Testing for sulfate ions in dilute sulfuric acid solution. Add barium chloride to dilute sulfuric acid solution. It will give a white precipitate, barium sulfate. Separate the precipitate from the solution and add a dilute acid such as HCl to the precipitate. Precipitate does not dissolve in dilute acid.

Acid Sulphate Soils: Formation, Classification and Management

1 天前  Acid sulphate soils form due to oxidation of sulphides in soils. The slow oxidation of mineral sulphides in soils is non-biological until soil pH reaches an acidity of pH 4.0, but the process is not well understood. Below pH 4.0, the bacteria, Thiobacillus ferroxidans are the most active oxidizers and the activity builds up rapidly.
