I am doing some research in catalytic ozonation for degradation/mineralization of organic pollutants. TOC data is more important in such research. I use TBA as an organic hydroxyl radical scavenger but it also contributes to TOC which falsify the actual data. so anyone please can suggest me an inorganic scavenger except carbonate and bicarbonate?
Try working with chloride ions.
Have a read to it.

Well! Bromide can heavily quench hydroxyl radical generated during AOPs, however, it might contribute to the degradation of the organic compounds. I suggest using a known amount of MeOH, a well known quenching agent, to all samples before TOC measurements. Use subtraction of a blank MeOH to get the actual TOC of your samples.
