Short summary
Cadmium is one of heavy metals that can cause serious health complications if humans are excessively exposed. This research was conducted to detect the amount of cadmium inside herbal plants using a new sensor modified with graphene and ionic liquid. The amount of cadmium inside herbs A, D, M and C were 0.0035, 0.0237, 0.0267 and 0.0251 milligrams/litre, respectively. The results showed that the herbs were safe to be consumed. The developed sensor was comparable to existing detection methods.
