Tavoitteena oli kehitell\u00e4 sopiva menetelm\u00e4 nallien liuottamiseen, jotta erilaiset nallimassoissa esiintyv\u00e4t komponentit saataisiin mitattua mahdollisimman hyvin. My\u00f6s liuotusprosessia yritettiin saada mahdollisimman lyhyeksi, jotta aikaa saataisiin s\u00e4\u00e4stetty\u00e4 liuotusprosessissa. Liuotukset jaettiin niiden esikokeisiin sek\u00e4 jatkoliuotuksiin, jotka kehiteltiin esikokeiden perusteella.

Yleisesti tuloksien perusteella 6 M typpihapolla totaaliliuottaminen sek\u00e4 5 M hapoilla vaiheittainen liuottaminen olivat parhaimmat menetelm\u00e4t nallimassan liuottamiseen kokonaisuudessaan. Lis\u00e4ksi lyhyempi vaiheittainen liuotus oli hyv\u00e4 vaihtoehto nallimassan liuottamiseen. My\u00f6s joillakin yksitt\u00e4isill\u00e4 alkuaineilla natriumhydroksidi tai 1 M tai 5 M typpihappo oli tarpeeksi v\u00e4kev\u00e4\u00e4 hyvien tulosten saamiseen.
