【摘要】 研究了二溴对甲基偶氮甲磺与锶生成2:1兰色络合物进行钢中微量锶的测定.该法λ_max=638nm,摩尔吸光系数E₆₃₈=5.01×10⁴,锶量在0.02～0.34μg/L范围内服从比尔定律.方法已用于钢中微量锶的测定,结果满意.更多还原

【Abstract】 The determination of microstrontium in steel by a blue complex compound with dibromo-p-methyl-metliylsulfonazo and strontium in molar ratio of 2:1 has been studied.Its molar absorptivity is 5.01×104 at 638nm.Beer’s law is obeyed in range of 0.02~0.34 mg/L for strontium.This method has been applied to determination of microstrontium in steel with satisfactory results.更多还原
