摘 要: 通过测定麦草溶解浆中的铁含量 ,对 1 ,1 0 菲罗啉分光光度法和火焰原子吸收光谱法进行了探讨 ,研究了影响 1 ,1 0 菲罗啉光度法测定的影响因素。结果表明 ,标准比色溶液的pH值对纸浆中铁含量的测定结果具有重要影响。 The test methods of 1,10-pheiianthroline photometry and flame atomic absorption spectroscopy were examined through determining the iron content of dissolving pulps made from wheat straw. The factors of affecting the determination by 1, 10-phenanthroline photometric method were studied. The results showed that the determined iron content in pulp was affected significantly by the pH value of standard colorimetric solutions.
