Xaaladaha kaydinta

Ku kaydi bakhaar hawo leh oo engegan. U fiirso qoyaanka, iyo baakadaha waa in la xiraa. Si looga hortago burburka baakadaha.

Xasilooni

1. Budada crystalline acicular iftiin cad, dhadhan dhanaan iyo dareen gubasho. Uumigeedu waa jaale-cagaaran, leh dhadhamin qallafsan, iftiin iyo kulayl deggan, iyo hygroscopic. Waxay dhadhamaysaa dhanaan waxayna leedahay dareen gubasho. Waa oxidizing, iyo monomer selenium ayaa soo degdegi doona marka ay la kulanto wakiilka yaraynta organic. sun ah.

2. Si fudud ayaa loo dhimay selenium.

3. Isticmaal qalabka ilaalinta inta lagu jiro hawlgalka. U fiirso si aad si joogto ah u hubiso fiirsashada selenium ee hawada. Si joogto ah u hubi jidhkaaga. Sii cunto qani ku ah borotiinka iyo amino acids.

4. Hawo iyo qoyaan deggan. Maadaama ay aad u sun badan tahay, waxaa lagu talinayaa in si taxadar leh loo xakameeyo oo loo isticmaalo daboolka qiiqa.
