This communication describes a method to detect aluminum in gastric drugs by the naked eye using a microfluidic paper-based analytical device ([mu]PAD). Aluminum ions react with chrome azurol S (CAS) and cetyltrimethylammonium bromide (CTAB) to form a colored complex, which generates a colored band on the [mu]PAD. A printed ruler can be used to…
