The presented procedure consists of a hydrochloric acid pre-treatment and a subsequent thermal oxidation. The method is compared to other processes like dissolution in hydrofluoric acid combined with ICP OES, energy-dispersive X-ray fluorescence spectroscopy (EDXRF) or aqua regia treatment.enghttps://creativecommons.org/licenses/by-nc-nd/3.0/540Plant materialSilica determinationSilicon contentArticle
