This Part is applicable to the determination of nickel, cobalt and manganese content in nickel cobalt manganese composite hydrogenoxide. See Table 1 for the determination scope. 2 Method Summary Use hydrochloric acid to dissolve the test portion, use yttrium as the internal standard, and adopt an inductively coupled plasma atomic emission spectrometer to determine the elements to be analyzed. 3 Reagents Unless it is otherwise stated, only reagents confirmed to be analytically pure and pure water with an electrical resistivity of not less than 18.2 M  cm shall be used in the analysis. 3.1 Hydrochloric acid (ρ = 1.19 g/mL). 3.2 Nitric acid (ρ = 1.42 g/mL). 3.3 Hydrochloric acid (1 + 1). 3.4 Nitric acid (1 + 1). 3.5 Yttrium internal standard solution A (0.2 g/L): weigh-take 0.254 g of yttrium trioxide (wY2O3  99.99%) in a 300 mL beaker, add 20 mL of hydrochloric acid (3.1), heat to dissolve it, then, cool it. Transfer it to a 1,000 mL volumetric flask; use water to dilute to the scale and mix it well. 3.6 Yttrium internal standard solution B (2.00 g/mL): divide-take 2.00 mL of yttrium internal standard solution A (3.5), transfer it into a 200 mL volumetric flask; use water to dilute to the scale and mix it well. 3.7 Nickel standard stock solution: weigh-take 2.0000 g of pure nickel (wNi  99.99%) in a 300 mL beaker, add 40 mL of hydrochloric acid (3.1) and 5 mL of nitric acid (3.2); heat to dissolve it. Boil to remove nitrogen oxides, remove and cool it, then, use water to wash the watch glass and beaker wall. Transfer to a 500 mL volumetric flask, use water to dilute to the scale and mix it well. 1 mL of this solution contains 4 mg of nickel. 3.8 Cobalt standard stock solution: weigh-take 1.0000 g of pure cobalt (wCo  99.99%) in a 300 mL beaker, add 20 mL of hydrochloric acid (3.1) and 5 mL of nitric acid (3.2); heat to dissolve it. Boil to remove nitrogen oxides, remove and cool it, then, use water to wash the watch glass and beaker wall. Transfer to a 500 mL volumetric flask, use water to dilute to the scale and mix it well. 1 mL of this solution contains 2 mg of cobalt. 3.9 Manganese standard stock solution: weigh-take 1.0000 g of pure manganese (wMn  99.99%) in a 300 mL beaker, add 20 mL of hydrochloric acid (3.1) and 5 mL of nitric acid (3.2); heat to dissolve it. Boil to remove nitrogen oxides, remove and cool it, then, use water to wash the watch glass and beaker wall. Transfer to a 500 mL volumetric flask, use water to dilute to the scale and mix it well. 1 mL of this solution contains 2 mg of manganese. 3.10 Nickel cobalt manganese standard solution 955: accurately transfer-take 15.00 mL, 20.00 mL and 30.00 mL of nickel standard stock solution (3.7), and 2.00 mL, 3.00 mL and 5.00 mL of cobalt standard stock solution (3.8) and manganese standard stock solution (3.9) in a group of 200 mL volumetric flasks. Respectively add 2.00 mL of yttrium internal standard solution A (3.5), use water to dilute to the scale and mix it well. 3.11 Nickel cobalt manganese standard solution 811: accurately transfer-take 15.00 mL, 20.00 mL and 25.00 mL of nickel standard stock solution (3.7), and 5.00 mL, 7.00 mL and 10.00 mL of cobalt standard stock solution (3.8) and manganese standard stock solution (3.9) in a group of 200 mL volumetric flasks. Respectively add 2.00 mL of yttrium internal standard solution A (3.5), use water to dilute to the scale and mix it well. 3.12 Nickel cobalt manganese standard solution 523: accurately transfer-take 10.00 mL, 15.00 mL and 18.00 mL of nickel standard stock solution (3.7), and 10.00 mL, 12.00 mL and 15.00 mL of cobalt standard stock solution (3.8), and 10.00 mL, 15.00 mL and 20.00 mL of manganese standard stock solution (3.9) in a group of 200 mL volumetric flasks. Respectively add 2.00 mL of yttrium internal standard solution A (3.5), use water to dilute to the scale and mix it well. 3.13 Nickel cobalt manganese standard solution 424: accurately transfer-take 10.00 mL, 12.00 mL and 15.00 mL of nickel standard stock solution (3.7) and cobalt standard stock solution ......
