摘要: |
在pH3.8HOAc-NaOAc缓冲溶液中及100℃加热条件下,Rh(Ⅲ)强烈催化KIO4氧化亮绿褪色。亮绿于-0.60V处产生一灵敏的导数极谱波。据此,本文采用线性扫描导数示波极谱研究了这一新的指示反应,建立了一个检出限和测定范围分别为3.0×10-5μg/mL和6×10-5~2.0×10-3μg/mL铑的催化分析新方法,并用于试样分析。 |

Abstract: |
Under the conditions of pH3.8 acetate buffer solution at 100℃, Rh(Ⅲ) Strongly Catalyzed the redox reaction between brilliant green and KIO4, brilliant green exhibits a sensitl.e derivative Oscilloplarographic waye at-0.60 V vs. SCE. On these grounds, a novel and highly sensitive catalyticmethod for deteromination of Rh in the range of 0.06-2.0 μg/mL was proposed, with a detection limit of 0.03 μg/mL Rh. Rhodium in synthetic sample and catalyst analysed by this catalytic method showed excellent results. |
