Persulfate ammonium: Avv iyo muhiimadda ay leedahay wax ku ool ah

persulfate ammonium loo isticmaalaa in lagu dardar habka polymerization ah, iyo sidoo kale in ay soo degayaa inta lagu guda jiro diyaarinta masaxado, balaastigga iyo latex, in sawir, in Iagu ah oo looxyada ku wareeg daabacan. Qoraalkan waxaa mararka qaarkood loo isticmaalo jeermi iyo bleaching.

persulfate ammonium: guryaha Physico-kiimikada

Himreaktiv ka dhigan taarikada midab, mararka qaarkood la cado a cagaar. Wax yar L. ee H 2 O (42.7%) heerkulka a of 15,5 ° C. Inta lagu guda jiro kulaylinta ka sarreeya 120 darajo oo foomamka ammonium pirosernisty, halka oxygen la sii daayay. Waa in la ogaadaa in cusbo qalalan lagu kaydin karaa gebi ahaanba la cayimin, halka cusbo qoyan si degdeg ah hydrolyzed la sii daayo of ogsijiin iyo nitrogen. xal aqueous of xarunta bilaabaan inay hydrolyze, xataa heerkulka qolka, marka heerkulka ka soo baxdo habka ay burburtay waxaa la wanaajiyey. Si aad u yarayso daatay ah, in xal aqueous of persulfate ammonium lagu daray alum potassium ama sulfates biraha alkali.

persulfate ammonium: Avv

xal reagent A waa la diyaariyey by electrolysis of sulphate ammonium ee acid sulphate. Si arrintan loo sameeyo, waxay qaadan weel 20 cm ballaciisu yahay iyo mugga laba litir loo daadshay dhexdeeda 1.7 litir oo cokan xal ammonium sulfate iyo shan millilitir oo acid sulphate ah. Next, ey isku keentay waxaa la hoos geliyey electrolysis isticmaalaya electrodes ee xarigga platina sameeyey. Haddii habka of electrolysis bilaabaa inuu ku udgoonsado of hydroxide ammonium, ka dibna ku dar saddex ilaa shan ml of xal cokan of sulphate ammonium ee sulfate acid. Ka dib markii saddex ilaa afar saacadood kasta oo timaheedii ayay off electrodes hadda. Ka dib 24 saacadood electrolysis ayaa lagu daray 90 g of burburiyo ammonium sulfate iyo electrolysis ka socotay 70 saacadood kale. Inta lagu guda jiro xal electrolysis waxaa si joogto ah u kiciyey. The kiristaalo keentay of persulfate ammonium waxaa gooni iyo xal ka waxaa mar kale cokan sulphate ammonium oo sulphate acid acidified. dadajin The keentay waa qallalay, heerkulka a ma ka badan 40 digrii.

Sida caadiga ah, helay sida uu sheegay habka diyaarinta ma waxaa ku jira in ka badan 90% nadsernistogo ammonium, waxaa inta badan loo isticmaalaa sida oxidant ah. reagent A la uruuray hoose ee walxaha firfircoon kasteba si recrystallization. in ay 700 g oo cusbo kala diri ee mugga ah isku mid ah biyo diiran (40 ° C). Dheeraad ah, iyadoo la isticmaalayo warqad filter fluted, xal imtixaanka la sifeeyo, oo korkoodana waxaa filtrate la qaboojiyey. The kiristaalo keentay dembi way iska daahiriyeen persulfate ammonium sifeeyo on masaf Buchner ah oo biyo ku maydhay. diyaarinta ka helay guud ahaan waa buuxiya q.s.p. shahaadooyinka reagents

persulfate ammonium - Qarax iyo dab caddayn, laakiin ku kordhinaya sari ee walxaha kale. In geeddi-socodka ah ee gubista walxaha diiqayo iyo sunta. Xiriirka ayaa sheegay in reagent la walxaha guban kara lama oggola, taas oo la xiriirta oxidant xoog leh oo ay sameynayso wax guban, iyo sidoo kale wakiilada yareeyo. Inta lagu guda jiro kulaylinta persulphate ammonium si degdeg ah decomposes, this abuuraa badan oo gaas sun ah oo xoqe (oxides nitrogen, uumiga ammonia, oxides baaruud). heerka uu saamayn on jidhka bini'aadamka waa mid ka mid ah walxaha fasalka saddexaad oo halis. dose dulqaadan ugu badan ee deegaanka shaqada, waayo persulfate ammonium ah waa 0.1 mg halkii mitir cubic.

persulfate ammonium muujiyaan saamayn diiqayo on maqaarka iyo xub-axaleedka ee sanka, afka saabka, neef-mareenka, conjunctiva. Neefsasho oo ah walaxda dhirfinaya horumarinta cudurka neef. Marka sii dheerayn ama soo noqnoqda xiriir dhici dermatitis, canbaar, oo inta badan la socda dareen diidmo oo xasaasiyadeed, muujiyey sida urtikaria iyo shoog.

Marka la reagent lagama maarmaan ah ka shaqeeya si ay u isticmaalaan noocyo kala duwan oo qalab shakhsi ilaaliya (neefsado, ookiyaale caag, yuunifoomka).
