Standard Test Methods for Nickel in Water

These test methods cover the atomic absorption determination of nickel in water and wastewaters. This is accomplished by aspirating the sample directly following an hydrochloric-nitric acid digestion and filtration using a vacuum filtration device fitted with compatible membrane. Nickel is a silver-white metallic element seldom occurring in nature in the elemental form. Nickel salts are soluble and can occur as a leachate from nickel-bearing ores. Nickel salts are used in metal-plating and may be discharged to surface or ground waters. Nickel is considered to be relatively nontoxic to man and a limit for nickel is not included in the EPA National Interim Primary Drinking Water Regulation.

Analysis Type (Application Method): Atomic Absorption

Compatible Filters:

Vacuum glassware plus accessories typically use 25mm or 47mm membrane disks compatible with acidification Products suggested are the 0.45 μm Durapore® PVDF, 0.45 μm Isopore™ Polycarbonate PC, 0.45 μm Omnipore™ PTFE, or glass fiber AP15 (0.2-0.6 grading). Forceps to handle filter membrane.
