Plehra kimike - Përcaktimi i gjurmëve të elementëve - Përcaktimi i kromit (VI) nga metoda fotometrike (metoda A) dhe nga metoda e kromatografisë jonike (metoda B) me diktimin e spektrofotometrisë

Fertilizers - Determination of trace elements - Determination of chromium(VI) by photometry (method A) and by ion chromatography with spectrophotometric detection (method B)

95.99 Withdrawal of Standard 27 sht 2016

General information

Current stage: 95.99 Effective date: 27 sht 2016

Originator: DPS

Owner: DPS/KT 47

Type: European Norm

ICS: 65.080

Scope

This European Standard specifies two methods for the determination of the content of soluble chromate in fertilizers.
Method A specifies the determination of chromate after extraction with water by photometry. This method can be used to determine Cr(VI)-mass fractions in solids higher than 1 mg/kg.
Method B specifies the determination of chromate by alkaline digestion and ion chromatography with spectrophotometric detection. This method can be used to determine Cr(VI)-mass fractions in solids higher than 0,1 mg/kg.
NOTE In case of reducing or oxidizing fertilizer matrix, no valid Cr(VI) content can be reported.
