Abstract

Objective: A colloidal gold test strip method that can achieve on-site and rapid detection of cadmium elements in rice was established. Methods: Based on lateral immunochromatographic technology, the colloidal gold test strip was systematically optimized for a series of parameters that affect the detection performance. Results: The visual detection limit of cadmium in rice was reached at 10 ng/g with the colloidal gold test strip. In practical applications, the sample pretreatment process is simple, low concentration acid can be directly extracted and diluted for test strip detection. Conclusion: The colloidal gold test strip was suitable for on-site rapid screening ofcadmium in rice.
