AI Article Synopsis
- A new spectrophotometric method has been developed to detect trace amounts of manganese (Mn(II)) using alizarin green and potassium periodate with beta-cyclodextrin as a sensitizer.
- The method can measure Mn(II) concentrations in the range of 0-2.4 ng/mL, with a detection limit of 0.097 ng/mL and a relative standard deviation of 0.45%.
- This technique was successfully applied to analyze manganese levels in cereal and wine samples, showing promising outcomes.
Article Abstract
A new catalytic spectrophotometric method for the determination of trace amount of Mn(II) has been developed. The method is based on the oxidation of alizarin green(AG) by potassium periodate in the presence of beta-cylodexdrin(beta-CD) as a sensitizer and nitrilotriacetic acid as an activator. The linear range of the method was 0-2.4 ng x mL(-1) for Mn(II), the determination limit was 0.097 ng x mL(-1), the relative standard deviation was 0.45% (n = 12) for 1.6 ng x mL(-1) of Mn(II), and the sensitivity was increased by a factor of 2.5 compared to that in the absence of the beta-CD. The method was used for the determination of Mn(II) in cereal samples and wine samples with satisfactory results. The mechanism of this reaction system was also presented.
