以氧化石墨烯（GO）为载体，利用静电吸附将氨基修饰的Fe 3 O 4 磁性纳米颗粒负载到GO表面得到GO-Fe 3 O 4 复合材料，再通过静电作用将Au纳米颗粒与GO-Fe 3 O 4 复合材料组装，制备了Au/Fe 3 O 4 /GO复合材料，并考察其表面增强拉曼（SERS）活性.首先以罗丹明B（RhB）为探针分子，考察Au纳米颗粒的粒径对SERS性能的影响，发现平均粒径为40 nm的Au纳米颗粒具有最好的SERS效果.SERS检测性能随着Au负载量的提高而逐渐变优，Au/GO中Au负载量为20%时最优.以多环芳烃分子芘为探针分子，探究Au/Fe 3 O 4 /GO复合材料中各组分对SERS性能的影响发现，Au纳米颗粒对拉曼信号的增强起主要作用，GO可以通过化学增强效应及对芘的吸附富集作用有效提高SERS检出限，Fe 3 O 4 的存在可以使基底快速分离，简化实验步骤，便于基底重复利用.该方法对水溶液中芘的检出限达到10 -8 mol·L -1 ，相对于普通拉曼的检出限有了明显的降低，有望被用于环境中痕量多环芳烃的富集-检测.
