  • BWT tester trdote vode AQUATEST

    Trdota vode je lastnost, ki izraža vsebnost raztopljenih mineralov (najpogosteje CaO in MgO) v vodi. Trdota vode je pomembna za njeno uporabo kot pitne in uporabne vode. Je vir nastajanja vodnega kamna in vpliva tudi na okusne lastnosti vode. Lahko je trajna in prehodna. Trajna vsebuje raztopljene kloride, sulfide, nitrate in silikate. Prehodna vsebuje raztopljen Ca (HCO3) 2 (kalcijev hidrogenkarbonat). Po njegovem izločanju nastane CaCO3 (kalcijev karbonat), kar je vodni kamen.

    Navodila za uporabo

    1. Pred začetkom testa za določanje trdote pustite vodo odtekati približno 1 minuto. Napolnite epruveto do bele oznake.
    2. V vodo nakapajte 1–2 kapljici testne raztopine A (rjava steklenička), dobro pretresite in počakajte, da raztopina pordeči (svetlo vijolična).
    3. V vodo dodajajte raztopino B po eno kapljico, dokler se barva raztopine ne spremeni iz rdeče v svetlo modro.
    4. Vsaka kapljica raztopine B ustreza trdoti 1 ° dH (nemška stopinja). Če želite končno trdoto izraziti v drugih enotah, uporabite pretvorbeno tabelo v originalnih navodilih.

    Pred vsako uporabo raztopini A in B dobro pretresite!

    Tester preostale trdote:

    • Epruveto sperite s testirano vodo in jo napolnite do oznake 5 ml (po potrebi 10 ml).
    • Dodajte 1 (po potrebi 2) kapljici reagenta št. 1 in rahlo pretresite, da se premeša.
    • Dodajajte reagent št. 2 po posameznih kapljicah, dokler se barva tekočine ne spremeni iz rdeče v svetlo modro (po zadnji kapljici počakajte približno 15 sekund, ali se barva še spremeni).

    Ena kapljica reagenta št. 2 ustreza 0,1 ° dH pri vzorcu 5 ml in 0,05 ° dH pri vzorcu 10 ml. 1,0 ° dH = 0,18 mmol/l 5,6 ° dH = 1,0 mmol/l.
