【摘要】: Most waters rarely contain more than trace concentrations of cobalt from natural sources. Although trace amounts of cobalt seem to be essential to the nutrition of some animals, large amounts have pronounced toxic effects on both plant and animal life.1.1 These test methods cover the determination of dissolved and total recoverable cobalt in water and wastewater by atomic absorption spectrophotometry. Three test methods are included as follows:
Concentration Range
Sections
Test Method Ax2014;Atomic Absorption, Direct
0.1 to 10 mg/L
7 to 16
Test Method Bx2014;Atomic Absorption, Chelation-Extraction
10 to 1000 x03BC;g/L
17 to 26
Test Method Cx2014;Atomic Absorption, Graphite Furnace
5 to 100 x03BC;g/L
27 to 36
