How did you determined the TOC content ? If it is a oxidation method, H2O2 can consume some oxidant (e.g. permanganate) with oxygen evolution.

Emmanuel Ushie

Many thank everyone for your contribution, The IC column was clogged and needed cleaning. I have it sorted now.

Antonio Eduardo Da Hora Machado

Dear Emmanuel,

Before a TOC analysis we add a Na2SO3 solution to the samples, according to the stoichiometry between H2O2 and Na2SO3, and H2O2 concentration, ensuring the removal of the remaining H2O2.

See the references i attached.

Best Regards,

Antonio Eduardo

Very many thanks Antonio. This was certainly helpful.
