一般描述
氢氧化钠（苛性钠，NaOH）是一种水溶性无机碱，具有广泛的工业应用，如滴定方法、溶解测试和 pH 调节。它也被用作沉淀剂，以沉淀过渡金属氢氧化物。
应用
氢氧化钠作为试剂：
- 在水热合成LTA沸石晶体形成过程中，制备合成溶液。
- 在合成二线水合铁(spHm)和菱形水合铁(rhHm)时，可作为调节混合溶液pH的碱。
- 在纳米颗粒(CRNP)分析和合成的催化反应过程中，提高HEPES缓冲液的pH值。
- 由氯化锌合成氧化锌纳米颗粒，其中锂掺杂对纳米颗粒阴极发光性能产生影响。
- Alkaliptosis induction counteracts paclitaxel-resistant ovarian cancer cells: Utilizing sodium hydroxide in ATP6V0D1-mediated ABCB1 inhibition reveals a novel approach to overcoming drug resistance in ovarian cancer, promoting cell death through alkaliptosis. This could significantly impact cancer treatment strategies (Chen et al., 2024).
- Ozone-activated lignocellulose films blended with chitosan: Research shows potential for creating biodegradable, edible films using sodium hydroxide in the activation process. This application is particularly relevant in food packaging and could revolutionize how we approach sustainable material science (Ebrahimi et al., 2024).
- Stabilizing fish oil emulsions with tilapia head gelatins: Investigating the effects of sodium hydroxide in the extraction of gelatins, this study highlights its utility in enhancing the stability and usability of fish oil emulsions in food science (Li et al., 2024).
- Cellulose dissolution in ZnO/NaOH/Water solvent solution: Molecular dynamics simulation studies illustrate how sodium hydroxide aids in dissolving cellulose, with temperature-dependent effects providing insights into polymer science applications, especially in textile and material production (Bourassi et al., 2024).
- Recycling Metakaolin/Slag-Based Geopolymer Concrete: Sodium hydroxide plays a crucial role in developing geopolymer concretes capable of withstanding severe freeze-thaw conditions, suggesting significant applications in sustainable construction materials (Liu et al., 2024).
