Samples of marketed Lauha bhasma from different manufactures were evaluated chemically. Apart from the 81 -85% iron content, the 15-19% other constituents were determined therein. Ferrous ferric and total iron in a single aliquot were determined spectrophotometrically, Qualitative and chromatographic analysis indicate the presence of sodium, potassium, calcium copper and cobalt in the samples, silicious matter and traces of ascorbic acid were present while tannin was absent in Lauha bhasma . Quantitatively sodium and potassium were determined by flame spectrometry. Upon fractionation, water soluble and acid soluble contents were determined.
对来自不同制造商的市售铁煅灰样品进行了化学评估。除了81 - 85%的铁含量外，还测定了其中15 - 19%的其他成分。用分光光度法测定了单份试样中的亚铁、三价铁和总铁含量。定性和色谱分析表明样品中存在钠、钾、钙、铜和钴，铁煅灰中存在硅质物质和微量抗坏血酸，而不存在单宁。通过火焰光谱法对钠和钾进行了定量测定。分级分离后，测定了水溶性和酸溶性成分。
