Embodiment 1
[0035] The content of chromium and aluminum in nickel-chromium-aluminum-coated diatomite is determined by using an inductively coupled plasma emission spectrometer (French JY170). The working conditions and analysis lines of the instrument are as follows: high-frequency frequency: 40.68MHz; incident power: 1.0Kw; reflected power : <15W; argon gas flow: cooling gas flow: 15L / min; sheath gas flow: 0.2L / min; incident slit: 20μm; exit slit: 80μm; 2s; element analysis line: chromium 267.716nm, aluminum 394.401nm;
[0036] (1) The reagents used in the determination process are as follows:
[0037] (1.1), hydrochloric acid, ρ1.19g / mL, superior grade or high purity or MOS grade;
[0038] (1.2), nitric acid, ρ1.42g / mL, superior grade or high purity or MOS grade;
[0039] (1.3), hydrofluoric acid, ρ about 1.15g / mL, excellent grade or high purity or MOS grade;
[0040] (1.4), chromium standard solution with a mass fraction not less than 99.99%: 1.00mg / mL, weigh 0.5000g of high-purity ...
Embodiment 2
[0056] The content of chromium and aluminum in nickel-chromium-aluminum-coated diatomite is determined by using an inductively coupled plasma emission spectrometer (IRIS intrepid II in the United States). The working conditions and analysis lines of the instrument are as follows: high-frequency frequency: 40.68MHz; incident power: 1.15Kw ; Reflected power: <15W; Argon gas flow: cooling gas flow: 15L / min; auxiliary gas flow: 1.0L / min; pump speed: flushing pump speed 120rpm (2.22ml / min); analysis pump speed 120rpm (2.22ml / min min); UV integration time: 3s; element analysis line: chromium 267.716nm, aluminum 394.401nm;
[0057] (1) The reagents used in the determination process are as follows:
[0058] (1.1), hydrochloric acid, ρ1.19g / mL, superior grade or high purity or MOS grade;
[0059] (1.2), nitric acid, ρ1.42g / mL, superior grade or high purity or MOS grade;
[0060] (1.3), hydrofluoric acid, ρ about 1.15g / mL, excellent grade or high purity or MOS grade;
[0061] (1.4), ...
