8 Content of contract (or ordering list)
The following content shall be included in contract (or ordering list).
a) product name;
b) quantity;
c) the number of this Standard;
d) others.
A.2.11 Standard mixture solution B. Get 10.00mL of standard mixture solution A (A.2.10);
place it into 100mL flasks. Add 20mL of nitric acid (A.2.4); dilute it to scale; shake it evenly.
1mL of this solution contains 10μg of ferrum, zinc and chromium elements.
A.3 Instrument and materials
A.3.1 Inductively coupled plasma atomic emission spectrograph.
A.3.2 Ultrasonic wave generator (power capacity 100W, frequency 40kHz).
A.3.3 Magnetic bar (6000Gs~8500Gs, φ30mm×100mm).
A.3, 4 Argon [φ (Ar)≥99.999%].
A.4 Samples
Battery grade lithium carbonate.
A.5 Analysis Steps
A.5.1 Samples
Weigh 200g~250g of the sample, accurate to 0.1g; make parallel sample at the same
time.
A.5.2 Blank Test
Carry out a blank test for the accompanying samples.
A.5.3 Determination
A.5.3.1 Weigh sample material (A.5.1); place it in a 500mL jar. Put the magnetic bar into
the plastic jar; add 250mL of first-grade water slowly (A.2.1). Put electric blender into the
jar; blend for 30min at speed of 100r/min.
A.5.3.2 Take out the magnetic bar; clean the lithium product on surface of the magnetic
bar by using water. Put the magnetic bar into a 500mL glass flask; add 150mL~200mL of
water. Then clean it for 20min by using ultrasonic wave.
A.5.3.3 Add 15mL of prepared aqua regia (A.2.6) into a glass flask; heat it on heating plate
until it boils mildly for 20min. Cool it to room temperature.
A.5.3.4 Take out the magnetic bar from the glass flask; wash it for 3~5 times with water.
Transfer the sample solution into a 250mL flask for constant volume determination. Carry
out measurement for the sample solution as well as blank solution (A.5.2) with plasma
spectrograph according to the spectral line given in Table A.1
