    摘要:
    异糖精酸是高碱性水泥孔隙水条件下纤维素降解的主要最终产物,众所周知,它可以通过形成强络合物来增加锕系元素的流动性。在本研究中,Am(III) 配合物与 α- d的形成通过结合分光光度法、时间分辨激光荧光光谱 (TRLFS) 和密度泛函理论 (DFT) 计算,从热力学和配位结构方面对异糖精 (ISA) 进行了研究。Am(III)–ISA 配合物的形成常数通过吸收光谱在 15–70 °C 的温度范围内测定。测得的反应焓和熵变化表明,1:1 Am(III)-ISA 复合物的形成是由熵增加驱动的。相比之下,1:2 复合物的形成是放热的,熵的增加要少得多。DFT 计算预测 C2 和 C4 羟基与羧基一起参与一级 ISA 的三齿螯合物结合。热力学,TRLFS,

    Complexation of Calcium by alpha-Isosaccharinic Acid under Alkaline Conditions.
    摘要:
    The complexation of Ca2+ by alpha-isosaccharinic acid (alpha-ISA) was determined by measuring the solubility of Ca(alpha-ISA), as a function of pH. In the pH range between 12 and 12.8, the observed increase of the total concentration of Ca in solution with increasing pH is explained by the complexation reaction:Ca2+ + alpha-ISA(-) = Ca(alpha-ISA(-H))(0) + H+with log K-CaISAo(o)=-10.4 (s=0.2) at I=0. In addition to this complexation reaction, another complex is postulated:Ca2+ + alpha-ISA(-) reversible arrow Ca(alpha-ISA)(+)with log K-CaISA+(o)=1.70. A value for the solubility product of Ca(B-ISA), is calculated: log K-sol(o)=-6.36 (s=0.1) at I=0.

    Isosaccharinic acid, a major final product of cellulose degradation under highly alkaline cement porewater conditions, is known to increase the mobility of actinides via strong complex formation. In this study, the formation of Am(III) complexes with α-d-isosaccharinate (ISA) was studied in terms of thermodynamics and coordination structures by combining spectrophotometry, time-resolved laser fluorescence
