【摘要】 采用红外吸收法可同时测出水垢等无机盐中碳酸根、硫酸根含量、并具有测量范围宽、周期短、灵敏度、准确度高等优点。红外吸收法测定碳酸根结果的相对误差小于 1.0 0 %。更多还原

【Abstract】 The direct combustion IR spectrometric method was applied to the determination of carbonates (as carbon) and sulfates (as sulfur) in boiler scale. The scale sample taken was dried and pulverized, and then transferred to the crucible for combustion in high frequency induction furnace. The determination of carbon and sulfur was concluded by IR spectrometry.更多还原
