概括

不敏感高爆炸物 (IHE) 在土壤中的残留物根据pH不同溶解. 在低pH雨水中,DNAN和RDX的溶解率下降,影响环境命运建模.

科学领域:

环境化学环境化学
土壤科学土壤科学
能量材料能量材料

背景情况:

不敏感的高爆炸物 (IHE) 越来越多地用于安全.
IHE残留物的环境行为,特别是它们在土壤中溶解的情况,尚不清楚.
了解IHE解散对于评估培训场所的环境风险至关重要.

研究的目的:

通过实验测量不同pH值的水中IHE成分的溶解速率.
模拟IHE残留物通过不同类型的土壤的移动和浸出.
评估溶解速度对IHE环境运输的影响.

主要方法:

在pH值为5.0和6.5.5的水中对IHE颗粒 (DNAN,NTO,RDX) 进行溶解速率实验.
使用随机建模来模拟土壤浸出物中的IHE残留度.
进行了灵敏度分析,以确定溶解速率对大规模迁徙的影响.

主要成果:

NTO的溶解速度与pH无关.
随着pH值的下降,DNAN和RDX的溶解速率显著下降.

Sample Preparation for Analysis: Advanced Techniques

Accurate analysis of complex samples often requires advanced preparation techniques to achieve reliable and reproducible results. Samples containing inorganic or organic materials can be challenging to dissolve or decompose effectively. Standard sample preparation methods include acid digestion, fusion, dry ashing, and wet digestion.
Acid digestion with strong acids is commonly used to dissolve inorganic materials that are insoluble (do not dissolve) in water. This method can be useful for...
