Extraction of Anions and Cations from Recent Volcanic Ash
1971
Bornemisza, Elemer
Water extracts of ash from Mt. Arenal, Costa Rica's most recently active volcano, contained up to 32 ppm Ca, 3.3 ppm Mg, 4 ppm K, 4 ppm Na, and 0.4 ppm Mn. No phosphates were extracted by water, but sulfates reached 35 ppm and silicates 1.6 ppm in the extracts. The sample farthest away from the volcano gave extracts of lowest Ca and Mg content. The pH of diluted NaOH suspension of ash decreased on standing by up to 1.5 pH units.
