## Abstract This study describes the simultaneous determination of phosphonate, phosphate, and diphosphate by CE with direct UV detection, based on inβcapillary complexation with Mo(VI). When a mixture of phosphonate, phosphate, and diphosphate was injected into a capillary containing 3.0 mM Mo(VI)
## Abstract A facile, sensitive, and selective method was developed for the simultaneous separation and determination of copper(I) [Cu^+^] and copper(II) [Cu^2+^] ions using CE with direct UV detection. The copper ions were complexed with a 1.5β mM bicinchoninic acid disodium salt solution at pHβ 8.7
