What is BS EN 1233 — Determination of chromium about?
BS EN 1233 specifies two methods for the determination of chromium in water by atomic absorption spectrometry. The two methods are covered in separate clauses as follows:
- Clause 3: Determination of chromium by flame atomic absorption spectrometry
- Clause 4: Determination of chromium by electrothermal atomization atomic absorption spectrometry
Clause 3 of BS EN 1233 is applicable to the analysis of water and wastewater when the concentration range is between 0,5 mg/l and 20 mg/l of chromium.
When the concentration is below 0,5 mg/l, the determination can be carried out after carefully evaporating an acidified sample to small volume, taking care to avoid the formation of a precipitate.
Clause 4 of BS EN 1233 is applicable to the analysis of water and waste water when the concentration range is between 5 mg/l and 100 mg/l of chromium by injecting a sample volume of 20 ml. It is applicable to the determination of higher concentrations by using a smaller sample volume.
Who is BS EN 1233 — Determination of chromium for?
BS EN 1233 on the Determination of chromium is useful for:
- Wastewater collecting systems
- Wastewater treatment plants
- Plants treating industrial wastewater
- Water supply treatment plants
Why should you use BS EN 1233— Determination of chromium?
Chromium occurs in water in the oxidation states III and VI. The two methods described determine chromium in both oxidation states, either as acid soluble chromium or as water soluble chromium, depending on the sample pretreatment.
BS EN 1233 provides methods based on the atomic absorption spectrometric measurement of the chromium content of the acidified sample in a nitrous oxide/acetylene flame.
BS EN 1233 describes methods and procedures for determining chromium present in raw water with atomic absorption spectrometric method.
BS EN 1233 provides you with apparatus, sampling, transport, storage, and preparation of test pieces, preparation of reagents and apparatus, pre-treatment of test pieces, test procedure, and much more.
The test methods and procedures provided by BS EN 1233 assist you in the determination of chromium in water and ensure reducing the risk of severe health issues.
With obedience and compliance to BS EN 1233, you can enhance the efficacy of the water and manufacture a standardized product.
