Abstract

The objective of this study is to investigate the effects of residual present-day high-grade fertilizers on human physiology. Volumetric and acoustic investigations on aqueous l-ascorbic acid (LAA) have been carried out in the presence of two fertilizers, potassium chloride (KCl) and diammonium hydrogen phosphate (DAP), to explore and analyze the solvation behavior and molecular interactions occurring in the ternary solutions [LAA + KCl/DAP + water]. Analysis of various volumetric parameters like apparent molar volume (V_ϕ), partial molar volume (V_ϕ⁰), and partial molar expansibility (E_ϕ⁰) indicates strong ion–solvent interaction. The magnitudes of Hepler’s constant mark LAA as a structure reformer in aqueous KCl and a structure breaker in aqueous DAP. Negative values of the apparent molar isentropic compressibility (K_s,ϕ) and its value at infinite dilution (E_s,ϕ⁰) show the loss of compressibility of the hydration spheres in comparison to bulk water. Transfer values as well as ion pair and triplet interactions have been evaluated. Hydration numbers have also been assessed by using Passynski’s acoustic technique. Removal of water from solvation spheres by electrolyte ions is proposed. These findings establish the dominance of ion–ion and ion–hydrophilic interactions in the examined systems.

探究存在磷酸氢二铵和氯化钾的抗坏血酸水溶液的体积和声学特性

本研究的目的是调查当今残留的高级化肥对人体生理的影响。在氯化钾（KCl）和磷酸氢二铵（DAP）这两种肥料存在的情况下，对抗坏血酸（LAA）水溶液进行了体积和声学研究，以探索和分析三元溶液 [LAA + KCl/DAP + 水] 中发生的溶解行为和分子相互作用。表观摩尔体积（Vϕ）、部分摩尔体积（Vϕ0）和部分摩尔膨胀率（Eϕ0）等各种体积参数的分析表明，离子与溶剂之间存在强烈的相互作用。赫普勒常数的大小表明 LAA 在氯化钾水溶液中是一种结构改造剂，而在磷酸二铵水溶液中则是一种结构破坏剂。表观摩尔等熵可压缩性（Ks,j）的负值及其无限稀释时的数值（Es,j0）表明水合球体的可压缩性比散装水要低。我们还评估了转移值以及离子对和三重相互作用。还使用帕辛斯基声学技术评估了水合数。提出了电解质离子去除溶解球中水分的方法。这些发现确定了离子-离子和离子-亲水相互作用在所研究体系中的主导地位。

期刊介绍： The Journal of Chemical & Engineering Data is a monthly journal devoted to the publication of data obtained from both experiment and computation, which are viewed as complementary. It is the only American Chemical Society journal primarily concerned with articles containing data on the phase behavior and the physical, thermodynamic, and transport properties of well-defined materials, including complex mixtures of known compositions. While environmental and biological samples are of interest, their compositions must be known and reproducible. As a result, adsorption on natural product materials does not generally fit within the scope of Journal of Chemical & Engineering Data.
