5%, Acros Organics), NaOH pellets (Sigma Aldrich), ammonium persulfate
(APS, 98%+, Sigma Aldrich), and potassium disulfite (KDS, Sigma Aldrich) were used without further purification.
2] nanocomposite has been prepared in the aqueous media using hydroxypropylcellulose as a steric stabilizer and ammonium persulfate
as an oxidant then dedoped with NH3(0.
In order to obtain the objectives, a nanocomposite containing poly (acrylamide-co-acrylonitrile) and silver nanoparticles was firstly synthesized by using ammonium persulfate
as the initiator and methylene bisacrylamide as the cross-linker.
3]) and reacting them with strong oxidizing agents such as ammonium persulfate
Sodium dodocylsulfate (Fluka) Ammonium persulfate
(Merck) Glycine (Fluka)
The samples were analyzed for iodine concentration using spectrophotometric measurement of iodine in the Sandell-Kolthoff reaction which involved an iodine catalyzed reduction of yellow ceric (IV) ions to colourless cerous (III) ions by ammonium persulfate
(Pino et al.
It is comprised of a peroxide-based developer component containing, by weight, approximately 6-12% hydrogen peroxide; a powder activator component comprised of 40-80% by weight of an alkali metal persulfate selected from the group consisting of sodium persulfate, potassium persulfate and ammonium persulfate
, an alkalizing agent component in an aqueous vehicle comprised of 3-25% of an alkalizing agent by weight; and a colorant present in an amount of from 0.
Materials with sources of supply utilized in this study are listed as follows: deionized water, n-butyl methacrylate (99+%), 10-55 ppm MEHQ (nBMA) (Aldrich); methacrylic acid (99%), 250 ppm MEHQ (MAA) (Aldrich); n-butyl acrylate (99%), 10-55 ppm MEHQ (nBA) (Aldrich); 1,3-butylene glycol dimethacrylate, 200 ppm MEHQ (1,3-BGDMA) (Aldrich); diacetone acrylamide, 99% (DAA) (Aldrich); adipic dihydrazide, 98% (ADDH) (Aldrich); sodium lauryl sulfate (SLS) [RHODAPON UB (30%), Rhone-Poulenc]; ammonium persulfate
After surfacing mill and polishing the surfaces were treated with a 20% Ammonium Persulfate
In this study, we tested three digestion methods on 200 urine samples from patients hospitalized at the La Timone University Hospital: the conventional chloric acid method (1); an acid ammonium persulfate
method (3, 4); and a method involving a HN[O.
Immediately after the incorporation of the ammonium persulfate
and TEMED, the gel solution is mixed and poured directly between the glass plates.
