Additionally, the diphenylamine
test did not reveal presence of nitrates in the NPs colloidal solution after the third stage of centrifugation (Figure 4(a)).
Thereafter a 1 cm long hollow-fibre membrane filled with toluene acceptor solvent (prespiked with the diphenylamine
internal standard) fitted at the tip of the Hamilton[R] syringe was introduced carefully into the solution and the vial was tightly capped.
Visualization of the bands was achieved bydrying the TLC plate at 120 C for 1 hour after reacting the plate with a solution consisting of 5 ml of acetone, 0.1 ml of aniline, 0.1 g of diphenylamine
and 0.75 ml of phosphoric acid (85%).
Silver and gold nanoparticles were synthesized from silver neodecanoate and gold (I) sodium thiosulfate, respectively,in presence of DPA-NDI-SH (where DPA= Diphenylamine
) in a single reaction vessel.
The amount of DNA fragmentation in cancer cells was quantified using diphenylamine
Venkatachari, "Investigation of the inhibitive effect of poly(diphenylamine
) on corrosion of iron in 0.5 M H2SO4 solutions," Journal of Electroanalytical Chemistry, vol.
From all the synthesized derivatives 27(a-j), the compound 27h containing morpholine moiety was found to be most active followed by the compound 27i with piperazine moiety and compound 27e with diphenylamine
DNA content in the supernatant was determined using the method of diphenylamine
reaction and expressed as the amount of DNA mg/g of wet weight of bone tissue .
DNA was determined by treating the nucleic acid extract with diphenylamine
reagent and the intensity of blue colour was measured at 600 nm.
(1949): Further Observations on the Diphenylamine
Test for Gun Powder Residue.
Double base smokeless powders typically contain nitrocellulose, dibutyl phthalate, diphenylamine
, ethyl centralite, waxes and other hydrocarbon-based additives (Western 2007).
In this method a protein precipitate of serum containing sialic acid will react with diphenylamine
producing a purple colour, which is quantitatively measured on a spectrophotometer at 540 nm.
