Description
One, technical field
The invention belongs to technical field of analytical chemistry, relate to the quantitative analysis tech of lanthanum, cerium in a kind of rare earth silicon ferro-aluminum.
Two, background technology
The rare earth silicon ferro-aluminum is mainly used in deoxidation, inclusion modification and microalloying effect in smelting process.Because the special role and the cost of lanthanum, cerium are higher, it is extremely important therefore accurately to measure its content, and at present, the analysis of lanthanum, cerium does not still have standard method in the rare earth silicon ferro-aluminum, and we have invented this method through experiment.
Three, summary of the invention
The objective of the invention is to disclose the assay method of lanthanum, cerium content in a kind of rare earth silicon ferro-aluminum, utilize this method can accurately measure the content of lanthanum, cerium in the rare earth silicon ferro-aluminum.
At first, confirm the span of correlation parameter through experiment and to the influence factor of assay method.
1, the selection of instrument test condition
With the mixed standard solution that contains lanthanum, cerium, carry out the condition test of power, atomization gas flow, cooling gas flow, mensuration mode (axially, radially) etc. successively, the result shows:
1) along with the increase (increasing to 1450W from 1000W) of power, line strength of lanthanum, cerium increases, and background intensity also increases;
2) cooling gas flow increases to 0.4L/min from 0.1L/min, and line strength of lanthanum, cerium does not have significant change;
3) the atomization gas flow increases to 1.20L/min from 0.70L/min, wherein increases to 0.95L/min by 0.75L/min, and line strength of lanthanum, cerium obviously reduces, and increases to 1.20L/min from 0.95L/min, and line strength of lanthanum, cerium does not have significant change.
According to the combined influence degree of factors such as power, atomization gas flow, cooling gas flow, lanthanum, cerium character and high low content to the mensuration result; It is test condition that the related data that line strength is big, background is low is selected in decision; Selection result is: power 1300W, atomization gas flow 0.80L/min, cooling gas flow 0.2L/min, adopt radially and measure.
2, the selection of analysis spectral line
Adopt the single element titer of a certain amount of lanthanum, cerium and contain lanthanum, the cerium mixed standard solution of a certain amount of aluminium, iron-based; Analysis spectral line to lanthanum, cerium scans respectively; Select peak shape good, disturb less, spectral line that background is low is as the analytical line of lanthanum, cerium, i.e. La 408.672nm; Ce 418.660nm.
3, coexistence elements interference experiment
Because the rare earth silicon ferro-aluminum when dissolved samples, adopts nitration mixture such as hydrofluorite, in course of dissolution, silicon disperses with the SiF4 form, and therefore, the content of silicon is extremely low in the mensuration system, does not influence the mensuration of lanthanum, cerium content.
3.1 the influence that matrix element aluminium is measured lanthanum, cerium content
Pipette lanthanum, cerium standard solution 5.00mL that concentration is 1.0mg/mL respectively; Add 0.00%, 10.00%, 20.00%, 30.00% aluminum standard solution successively; Carry out the mensuration of lanthanum, cerium content by experimental technique; Each element determination recovery all within 95%～105% scope, is measured the result and is seen table 1.

| La | 4.98 | 5.02 | 4.99 | 4.97 |
| Ce | 5.02 | 5.00 | 4.99 | 4.96 |
Mensuration result shows: when calcium≤30.00%, the mensuration of lanthanum, cerium content is not had remarkable interference.Because the content of aluminium is about 50% in the Alsimin, therefore, when the preparation working curve, coupling content is 30% aluminium.
3.2 the influence that matrix element iron is measured lanthanum, cerium content
Pipette lanthanum, cerium standard solution 5.00mL that concentration is 1.0mg/mL respectively; Add 0.00%, 5.00%, 10.00%, 15.00% iron standard solution successively; Carry out lanthanum, cerium mensuration by experimental technique; The mensuration recovery of lanthanum, cerium all within 95%～105% scope, is measured the result and is seen table 2.
Table 2: matrix element iron influence %
Mensuration result shows: when iron≤15.00%, the mensuration of lanthanum, cerium is not had remarkable interference.Because the content of iron is about 30% in the Alsimin, therefore, when the preparation working curve, coupling content is 15% iron.
3.3 hydrofluorite is to the influence of lanthanum, cerium
Pipette lanthanum, cerium standard solution 0.50,1.00,5.00,8.00mL that concentration is 1.0mg/mL respectively; Be placed in 4 300mL polytetrafluoroethylene beakers; By experimental technique dissolve, be fuming, constant volume, employing inductive coupling plasma emission spectrograph measure lanthanum, cerium, measure the result and see table 3.
Table 3: hydrofluorite is to the % that influences of lanthanum, cerium
Mensuration result shows: fluorine does not produce interference (fluorine and rare earth do not generate deposition, so do not influence its accurate mensuration) to the mensuration of content of rare earth during sample dissolution.
3.4 the interference of coexistence elements
Standard solution with lanthanum, each element of cerium; Add respectively and be equivalent to contain in the 0.1000g sample 5.00% Mg, Ca, V, 3.00% P, Mn, Ti, 1.00% Ni, Nb; 0.50% Mo; 0.20% Cr, Cu carry out the interference test between element, and the result shows: when Mg≤5%, Ca≤5%, P≤3%, Mn≤3%, Ti≤3.00%, V≤5.00%, Ni, Nb≤1%,, Mo≤0.5%;, Cr, Cu≤0.2% o'clock do not disturb the mensuration of lanthanum, cerium content, measure the result and see table 4.
