Use of a Ca-selective electrode in the determination of total Ca in the production of crude sugar. Preliminary studies

The determination of the total calcium in juice, syrups, and other products of the sugar industry is investigated. Total calcium and free calcium is determinated by AAS and employing Ca-selective electrode respectively. A coefficient is obtained for the relation of total calcium with respect to free...

Description
Summary:The determination of the total calcium in juice, syrups, and other products of the sugar industry is investigated. Total calcium and free calcium is determinated by AAS and employing Ca-selective electrode respectively. A coefficient is obtained for the relation of total calcium with respect to free calcium. The coefficient is employed to determine the content of total calcium in accordance with the following equation. Foi investigada a determinação do total de cálcio em sucos, melaços, xaropes e outros produtos da indústria açucareira. O cálcio total eo cálcio livre foram determinados, respectivamente, por espectroscopia de absorção atômica (AAS) e empregado eletrodo seletivo de cálcio. Foi obtido no coeficiente para relação entre o cálcio total e o cálcio livre. Este coeficiente foi utilizado na determinação do conteúdo total de cálcio, segundo equação:
