M\u00e9thode bas\u00e9e sur celle d\u00e9crite par Gindler, Heth et Khayam-Bashi. La calmagite (acide 1-[1-hydroxy-4-methyl-2-phenylazo]-2-naphtol-4-sulfonique), un indicateur m\u00e9tallochromique, forme un complexe color\u00e9, en milieu alcalin, avec le magn\u00e9sium. L\u2019absorbance du complexe est mesur\u00e9e \u00e0 510-550 nm et est proportionnelle \u00e0 la concentration en magn\u00e9sium dans le sp\u00e9cimen. L\u2019EGTA limite l\u2019interf\u00e9rence du calcium, tandis que le cyanure de potassium (KCN) r\u00e9duit celle des m\u00e9taux lourds. Le polyvinylpyrolidone (PVP) et un tensio-actif r\u00e9duisent l\u2019interf\u00e9rence des prot\u00e9ines et de la lip\u00e9mie.<\/p>\n
