Pathway 1: HCOOH
[right arrow] C[O.sub.2] + 2[H.sup.+] + 2[e.sup.-]
The ENR was synthesized via in situ latex epoxidation of NR by performic acid generated from the reaction between HCOOH
The chromatographic step was performed with a constant flow rate of 0.2 ml/min and a 45 min linear gradient from solvent A to solvent B (95% MeCN (v/v), 0.5% (v/v) HCOOH
H2O + CO[2.sup.-] [right arrow] HCOOH
+ 1/2 O2 + [e.sup.-]
Both CO and HCOOH
act as OH* radical scavengers and reducing agents.
Different desorbing agents like 1N NaOH, 1N HCl, triple distilled water and 85% HCOOH
were used for the desorption studies.
FT-IR spectra and TG curves indicated that the main evolved gases were C[O.sub.2] and [H.sub.2]O, while there were many minor gases, such as C[O.sub.2], C[H.sub.4], [C.sub.2][H.sub.6], C[H.sub.3]OH, C[H.sub.3]COOH, and HCOOH
The presentation includes both consecutive and parallel processes, and the reaction between formaldehyde molecule (HCHO) and (O) to form either formic acide (HCOOH
) or (HCHO...O) was assumed to be the rate controlling process.
Afterwards, 5 [micro]L of 35% [H.sub.2]O / 60% ACN / 5% HCOOH
were added and the mixture vigorously agitated for 15 min in order to extract tryptic peptides.
