42、nherent in a laboratory, both general and specific, this procedure shall only be carried out by fully trained personnel, or for those in the course of training, under the full supervision of trained personnel. A.l Scope This method specifies the determination of the percentage of free lead (metallic
43、 lead) in litharge and battery lead oxide (Barton and Mill). The lead monoxide content is calculated as specified in A.6.2. A.2 Principle A weighed test portion is treated with acetic acid in order to dissolve the lead monoxide. Any undissolved lead dioxide (PbOz) is reduced in ascorbic acid. A.3 Ap

48、ransfer quantitatively to A.5.2.2 Add 250 ml of acetic acid 20 % (volume fraction) (A.4.4) and warm gently with shaking, until dissolution of the oxide in the sample is complete: any free lead will remain as a sediment. If the solution has a red-brown colour caused by lead dioxide (PbQ), add ascorbi
49、c acid solution (A.4.5) dropwise until the red-brown colour is discharged. A.5.2.3 discard the bulk of the supematant liquid, ensuring that none of the sediment is lost. After any red-brown colour has disappeared, allow 5 min for all particles to settle, then decant and A.5.2.4 the transfer of all the sediment. Filter the remaining contents of the flask through a pre-weighed sintered glass filter (A.3.3), ensuring A.5.2.5 Wash the sediment retained on the filter four times with cold water and finally with acetone.
