Disposable screen-printed antimony film electrode modified with carbon nanotubes/ionic liquid for electrochemical stripping measurement

► We developed disposable screen-printed antimony film electrodes modified with MWCNTs and IL. ► The proposed electrodes provided well-define signals with very low background for heavy metals. ► We demonstrated that the modified SPSbFE could provide more sensitive responses than the bare one. ► This greatly expands the scope to conveniently develop ultrasensitive antimony electrodes.
