Abstract

This study aimed to develop a method for elemental determination in molasses samples by inductively coupled plasma optical emission spectrometry. The sample preparation occurred with a simple dilution, and the diluent solution's proportion was achieved through a simplex centroid design. For 0.200 g of sample, the components proportion was 60 % of 1.0 mol L⁻¹ HNO₃, 24 % of 10 % (v v⁻¹) H₂O₂, and 16 % of 1.0 mol L⁻¹ HCl. Applying the recommended dilution, the limits of detection were 0.50, 0.01, 0.02, 0.06, 0.05, 0.56, 1.20, 0.19, 0.092 mg kg⁻¹ for Zn, Co, Cd, Mn, Cr, Al, Na, Pb, and Cu, respectively. The procedure was applied to the analysis of cane molasses samples, and the concentrations obtained using the proposed procedure agreed with the results obtained using microwave-assisted digestion. The method was aligned with green analytical chemistry principles, achieving scores of 0.57 and 0.78 in the AGREE and AGREEprep metrics, respectively.

简单稀释后电感耦合等离子体发射光谱法测定甘蔗糖蜜样品中的绿色多元素

建立了电感耦合等离子体发射光谱法测定糖蜜样品中元素的方法。样品的制备采用简单的稀释，稀释溶液的比例通过单形质心设计得到。 0.200 g的示例中,组件是60 %的比例1.0 摩尔硝酸 L−1,24 % 10 % (v v−1)过氧化氢和16 % 1.0 摩尔 L−1盐酸。采用推荐稀释度，Zn、Co、Cd、Mn、Cr、Al、Na、Pb、Cu的检出限分别为0.50、0.01、0.02、0.06、0.05、0.56、1.20、0.19、0.092 mg kg−1。该方法应用于甘蔗糖蜜样品的分析，使用该方法获得的浓度与使用微波辅助消化获得的结果一致。该方法符合绿色分析化学原理，在AGREE和AGREEprep指标中分别获得0.57和0.78分。
