Abstract[English]
A method of extracting calcium ions from soil including: mixing soil with a solvent to produce a soil slurry; mixing the soil slurry with ammonium acetate to produce an extracted sample; filtering the extracted sample to produce a first filtrate; mixing the first filtrate with a precipitation reagent to produce precipitated calcium oxalate and a liquid solution; and separating the calcium oxalate from the liquid solution; wherein the precipitation reagent comprises from about 0.15 to about 0.35 M of an oxalate salt dissolved in a buffer having a pH from about 7.1 or more. Also, a system and a kit using the method.[French]
Un procédé d'extraction d'ions calcium du sol comprend les étapes consistant à : mélanger le sol avec un solvant pour produire une suspension de sol ; mélanger la suspension de sol avec de l'acétate d'ammonium pour produire un échantillon extrait ; filtrer l'échantillon extrait pour produire un premier filtrat ; mélanger le premier filtrat avec un réactif de précipitation pour produire de l'oxalate de calcium précipité et une solution liquide ; et séparer l'oxalate de calcium de la solution liquide ; le réactif de précipitation comprenant d'environ 0,15 à environ 0,35 M d'un sel d'oxalate dissous dans un tampon ayant un pH d'au moins environ 7,1. L'invention concerne également un système et un kit utilisant le procédé.
