Magnetic nano-carbon core shell was applied as mixed hemimicelle magnetic solid phase extraction adsorbent to introduce a novel sample preparation method for determination of acrylamide from potato chips. Acrylamide is identified as neurotoxic, a probable human carcinogen (group 2A) compound. Effective extraction parameters such as type and amount of extracting solvent, type and amount of adsorbent, time of extraction and desorption, the effect of pH, time of ionic liquid loading on the adsorbent and stirring rate (rpm) were studied and optimized. Under optimized extraction conditions, a good linearity was observed in the concentration range of 100–1500 ng/g. Limit of detection was observed as 30 ng/g. Application of the proposed method was surveyed by analysis of some potato chips brands available in the local supermarkets. The satisfactory results with the recovery of 95.58% revealed that the proposed method could be applied in food analysis laboratories.

磁性纳米碳核壳作为高效混合半胶束固相萃取策略，用高效液相色谱法测定马铃薯片中的丙烯酰胺

以磁性纳米碳核壳为混合半胶束磁性固相萃取吸附剂，为马铃薯片中丙烯酰胺的测定提供了一种新的样品前处理方法。丙烯酰胺被确定为神经毒性的，可能是人类致癌物（2A组）化合物。研究并优化了有效的萃取参数，例如萃取溶剂的类型和量，吸附剂的类型和量，萃取和解吸的时间，pH值，离子液体负载时间对吸附剂的影响以及搅拌速率（rpm）。在最佳提取条件下，在100-1500 ng / g的浓度范围内观察到良好的线性。检出限为30 ng / g。通过分析当地超市中一些薯片品牌，对所提方法的应用进行了调查。
