It was followed by the addition of a calculated amount of potassium persulphate
(0.0041 mol/L) followed by the addition of acrylic acid (0.810 mol/L) and N, N'-methylene-bisacrylamide (0.0144 mol/L) with continuous stirring.
ABTS_ + was generated by reacting ABTS (7.4 mM) with potassium persulphate
and those spun ammonium with the persulphate
and solvent iron (which has dimethyiformamide.
The possibility of bleaching of jute at ambient temperature has been explored using sodium persulphate
as peroxygen booster.
Fibroblast 3T3 cell line was purchased from (NCCS, Pune), Pune, india, poly (2-Hydroxy ethyl metha acrylate), sodium meta bisulphate, potassium persulphate
, silver sulfate, sodium borohydrate, PBS 10%, Dulbecco's Modified Eagle Medium (DMEM) containing serum was purchased from Sigma-Aldrich.
A systematic review and meta-analysis of allergens responsible for allergic contact dermatitis found that the top five allergens in children and adolescents included nickel, ammonium persulphate
, gold sodium thiosulphate, thimerosal and p-toluenediamine.
This work is in continuation to our investigations pertaining to the role of Mn(II) and Co(II) as catalysts on oxidations by persulphate
The ABTS+ stock solution was prepared by reacting potassium persulphate
(2.45 mM) and ABTS+ (7 mM) then allowing the mixture to stand for minimum 16 h to generate ABTS+ free radicals.
mM potassium persulphate
and allowing the solution to stand in dark at room temperature for 12-18 hours before use.
Ascorbic acid, 2,27-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), acrylamide, ammonium persulphate
(APS), Tris-buffered saline, and glycine were purchased from Sigma Aldrich.
A 2mM AbTS stock solution containing 3.5 mM potassium persulphate
was prepared and was kept in the dark at room temperature for 16 h to allow the completion of radical generation and was then diluted with water (1: 29, v/v).
Hydrogels have been prepared from AXs extracted from wheat bran as controlled release matrices, which were synthesized via the oxidative cross-linking using either chemical (ferulic chloride and ammonium persulphate
) or enzymatic (laccase/[O.sub.2] and peroxidase/[H.sub.2][O.sub.2]) free radical-generating agents [25-27].
