摘要：

采用非稳态共沉淀方法制备了无定形的Ni/Al LDH纳米粒子，水热处理过程促进了无定形沉淀的结晶，从而得到稳定的六边片状Ni/Al LDH纳米粒子胶体分散体系。通过调整胶溶温度和胶溶时间控制Ni/Al LDH纳米粒子的形貌和尺寸，对比不同胶溶温度和胶溶时间下得到的样品，得出制备Ni/Al LDH纳米粒子的最佳条件为胶溶温度130 ℃，胶溶时间24 h。由于Ni/Al LDH纳米粒子独特的带电及结构性质，具有较好的吸附性能，可将其制作成固相萃取柱，实现纳米材料与样品前处理技术的有机结合，优化样品前处理技术。

Abstract:

We prepared Ni/Al layered double hydroxide (LDH) nanoparticles by nonsteady coprecipitation. Water heat treatment process accelerated the crystal of amorphous precipitation. We acquired stable hexagonal sheet Ni/Al LDH nanoparticle colloidal suspensions. We controlled the shape and size of Ni/Al LDH nanoparticles by adjusting peptization temperature and time. We further obtained the optimal peptization temperature of 130 ℃ and peptization time of 24 h for the preparation of Ni/Al LDH nanoparticles. Ni/Al LDH nanoparticles have better adsorption property because of their unique properties of net positive charge and structure and can be manufacured as a solid phase extraction adsorbent. This realizes the combination of nanocomposites with sample pretreatment technology and optimizes sample preprocessing technology.

Key words: solid phase extraction adsorbent, layered double hydroxides(LDHs), nonsteady coprecipitation, peptization
