BS 4258-9:1989

What is BS 4258-9- Chloride content of phosphoric acid for industrial use about?

BS 4258 discusses phosphoric acid for industrial use.  BS 4258-9 is the ninth part of the BS 4258 multi-series and discusses the determination of chloride content.

BS 4258-9 describes a potentiometric method for the determination of the chloride content of phosphoric acid (orthophosphoric acid) for industrial use. It is applicable to products having chloride contents of between 1 mg/kg and 1 500 mg/kg.

Who is BS 4258-9- Chloride content of phosphoric acid for industrial use for?

BS 4258-9 on determining chloride content of phosphoric acid for industrial use is useful for:

• Chemical manufacturers
• Fertilizers manufacturers
• Quality control personnel

Why should you use BS 4258-9- Chloride content of phosphoric acid for industrial use?

Phosphoric acid (PA) is an important industrial chemical used as an intermediate in the fertilizer industry, for metal surface treatment in the metallurgical industry, and as an additive in the food industry.

BS 4258-9 provides you with the reagants and apparatus required for the test method for the determination of the chloride content of phosphoric acid. BS 4258-9 guides you with the procedure and calculation of the test method. BS 4258-9 helps you to manufacture high-quality phosphoric acid.
