概括
香与汁的注入增强了重金属的提取,特别是,铁和. 亚酸显示金属提取量最小,所有输注均不构成非致癌性健康风险.
科学领域:
- 食品化学 食品化学
- 分析化学 分析化学
- 环境健康 环境健康
背景情况:
- 香是一种流行的草药茶,在世界各地消费.
- 了解化合物的提取过程,包括重金属等潜在污染物,对于消费者安全至关重要.
- 温度,浸泡时间和添加剂等因素可以影响提取产量.
研究的目的:
- 在香样本中确定九种重金属 (Cd,Co,Cr,Cu,Fe,Mn,Ni,Pb,Zn) 的总含量.
- 量化这些重金属在各种条件下 (温度,浸泡时间) 和添加剂 (酸,汁) 的提取到水注入中的数量.
- 为了评估与香注水中的重金属暴露相关的非致癌健康风险.
主要方法:
- 香及其注水中的重金属含量使用火焰原子吸收光谱法 (FAAS) 进行分析.
- 用不同的温度 (70,80,100°C) 和浸泡时间 (3,5,7分钟) 准备输液.
- 研究了添加酸和汁对金属提取的影响.
主要成果:
- 在香中分析的重金属总度的平均值被确定 (例如,Mn: 113.5 μg/g,Fe: 32.17 μg/g,Zn: 30.34 μg/g).
- ,和主要在纯水中提取 (高达100%).
- 汁显著增加了,铁和的提取,在所有温度下,汁的Fe提取率最高 (4.07-25.7%). 亚酸通常导致金属提取百分比最低.
- 在所有输液类型中,所有分析的金属的非致癌危险系数 (HQ) 在成人和儿童中均低于1,这表明没有显著的健康风险.
结论:
- 添加剂的选择和造条件显著影响从香中提取重金属.
- 汁有效提取某些重金属,如Cd,Fe和Pb,而酸的作用最小.
- 即使使用不同的制备方法和添加剂,对于分析的重金属而言,食用香注水被认为是安全的.

Extraction: Advanced Methods
553
Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

Masking and Demasking Agents
2.7K
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on...
