查询词典 absorbance

After dissolution, the Cr in samples was oxidized to Cr with KMnO4.Fe(superscript 3+) and Cu(superscript 2+) were masked with NH4HF2 and thiourea, respectively. In acid solution at pH 3.0-4.0, the I2 generated from the reaction of Cr and KI could form high-sensitivity blue complex with starch. The absorbance was measured spectrophotometrically at 590 nm.

样品溶解后，用KMnO4将Cr氧化为Cr，以NH4HF2掩蔽Fe(上标 3+)、硫脲掩蔽Cu(上标 2+)后，在pH3.0~4.0的酸性溶液中，Cr与KI作用后生成的I2遇到淀粉后形成灵敏度很高的蓝色络合物，此络合物最大吸收波长为590nm。
