- W2353687195 abstract "Cadmium(Ⅱ) reacts with congo red to form blue ion complexes in the BR pH 4.0~5.2 buffer solution.A method was established for determination of cadmium in landfill leachate by spectrophotometry with sulfhydryl cotton preconcentraction.The maximum positive absorption wavelength was at 604 nm and maximum negative absorption wavelength was at 492 nm.The linearities ranged from 0.10 mg/L to 2.80 mg/L(positive absorption) and from 0.10 mg/L to 3.40 mg/L(negative absorption).The method was sensitive at the positive and minus wavelengths overlapping absorption.The treatment of landfill leachate and interference of coexistent ion were discussed.The analytical parameters were optimized.The samples detective results of the method were on different with the results of atomic absorption spectrometry.The recoveries were 98.6%~104%." @default.
