PROCESS OF DETERMINATION OF IRON (III) AND ALUMINIUM (III) IN ACID LIQUORS

摘要

FIELD: analysis of materials. SUBSTANCE: sample is injected into flow of nitric acid, xylenole orange is added into flow and presence of iron is detected photometrically. After this flow is heated up to 60-70 C and summary content of aluminium (3⁺) and iron (3⁺) is detected photometrically. EFFECT: expanded application field. 1 dwg, 2 tbl
