    the thiosulphate used up the iodine produced, so you are looking for a chemical that can do similar reaction.

    I2 + 2e- ----> 2I- E = +0.54

    S4O6 2- + 2e -----> 2S2O3 2- E = +0.08 V

    Based on what is shown on electrode potential values, half cell that has emf of around 0.08 would substitute well for thiosulphate.
