摘要
以改性淀粉包膜尿素为模型,探讨用丁二酮肟比色法测定包膜尿素释放养分速率,以达到快速评价包膜尿素控制释放性能的目的。结果表明,丁二酮肟比色法测定包膜尿素释放养分速率可行,自制改性淀粉包膜尿素具有一定的控制释放性能。
Membrane coated Uurea was prepared with modified starch, and colorimetry with dimethylglyoxime was used to investigate the controlled release rate of urea. The purpose was to provide a fast analytical method to evaluate the controlled release property of membrane coated urea. The results showed that colorimetry with dimethylglyoxime was feasible to analyze release rate of urea.
