| Summary: | In this research, microcapsule material has been developed by encapsulating ?-Nitroso-?-
Naftol inside Ca-alginate. This microcapsule is expected to have a metal ion Cu2+ retention
property through the making of ?-Nitroso-?-Naftol complex. Various considerations that
influence both the capsule making and the retention properties have been studied. Capsule
which has a good spherical shape is acquired by using Na-alginate and CaCl2 with 1:1.5
ratio. The microcapsule which has been made have a 1.28 mg Cu2+/g retention capacity in
pH 7 with 20 minutes minimum contact time. This microcapsule has been tested to fill
minicolumn for developing preconcentration method based on flow injection analysis (FIA). |
