摘　　要：以氧化石墨(GO)和尿素为原料,采用水热法-浸泡法制备了三维石墨烯缓释尿素,并通过砂柱淋溶和二甲氨基苯甲醛分光光度法对其缓释性能进行了测试。测试结果表明:相比普通尿素,三维石墨烯缓释尿素具有较好的缓释效果,20d累积释放率为84.33%。Using graphite oxide(GO)and urea as raw materials,three-dimensional graphene sustained release urea was prepared by hydrothermal-immersion method,and its sustained release performance was tested by sand column leaching and dimethylaminobenzaldehyde spectrophotometry.The results showed that compared with ordinary urea,three-dimensional graphene sustained release urea had better sustained release effect,and the cumulative release rate was 84.33% in 20 days.
