This section applies to the determination of nickel, copper, iron, manganese, zinc, lead, arsenic and cadmium in the crude cobalt hydroxide. The measurement range is shown in Table 1.
Table 1 measurement range
Elemental determination range (mass fraction) /% Elemental determination range (mass fraction) /%
Nickel 0.10 ~ 5.00
Copper 0.10 ~ 10.00
Iron 0.10 ~ 5.00
Manganese 0.10 ~ 2.50
Zinc 0.050 ~ 3.00
Lead 0.020 ~ 0.20
Arsenic 0.020 ~ 0.30
Cadmium 0.0010 ~ 0.010
2 method summary
The sample is decomposed with hydrochloric acid, the emission intensity of each element is measured on an inductively coupled plasma atomic emission spectrometer in dilute hydrochloric acid medium,
According to the working curve method to calculate the mass fraction of each element.
3 reagent
Unless otherwise stated, only reagents identified as analytical grade were used in the analysis. The water used was either laboratory secondary water or water of comparable purity.
3.1 Ammonium hydrogen fluoride.
3.2 Hydrochloric acid (p = 1.19 g/mL).
3.3 Hydrochloric acid (1 1).
3.4 Nitric acid (1 1).
3.5 sodium hydroxide solution (200g/L). Weigh.200g of sodium hydroxide, placed in 500mL plastic beaker, dissolved in water, cooled to room temperature,
Moved into 1000mL plastic volumetric flask, dilute to the mark with water and mix well.
3.6 phenolphthalein ethanol solution (1g/L). Weigh 0.100g phenolphthalein, placed in 100mL beaker, dissolved in anhydrous ethanol, transferred to 100mL volume
Volumetric flask, diluted with ethanol to the mark, mix well.
3.7 Nickel standard stock solution Weigh 1.0000g of metallic nickel (wNi ≥ 99.95%) placed in 500mL beaker, add 20mL of nitric acid
(3.4). Cover the watch glass and heat to completely dissolve. Rinse the watch glass and cup wall with water and heat to boil away the nitrogen oxide. Remove and cool to
Room temperature. Into a 1000mL volumetric flask, diluted with water to the mark, mix well. 1 mL of this solution contains 1 mg of nickel.
3.8 copper standard stock solution Weigh 1.0000g metal copper (wCu ≥ 99.95%), placed in 400mL beaker, add 15mL nitric acid
(3.4), cover the watch glass, dissolve in low temperature, wash the watch glass and cup wall with water, heat to boil away the nitrogen oxides, remove and cool. Move in
