    • The electrode membrane was casted with cetyltrimethylammonium bromide (CTAB), dioctylphthalate (DOP), and 1-butyl-3-methylimidazolinium hexafluorophosphate (IL). 200mg of ionophore was weighed accurately and dispersed over 10 ml THF. 100 mg of PVC were then added into the mixture with constant stirring. Meanwhile 50 g of CTAB and 5 ml ionic liquid were added with 2 ml DOP. The glass plate was previously fixed with PVC in THF as adhesive. The solution was kept covered and allowed to evaporate slowly to form an homogeneous membrane. The membrane of 5 mm diameter was cut and mounted onto an electrode body (Fluka). Solutions of different concentrations were diluted from the stock standard 0.1 M sulfate solution
    • -1 M were prepared and 5 ml of 0.001 M KCl was added to each solution. The electrode potential of sulfate ISE was measured (n = 9) against the calomel electrode (Fluka)
