Methylene Blue Extraction Employing NanoPak-C All-Carbon Microbeads-Packed 3 mL SPE Columns, & Quantification Using Visible Spectrophotometry.

Methylene blue, a heterocyclic aromatic chemical compound is a member of the phenothiazines family and a cationic tricyclic phenothiazine salt. It is a well-known medication and organic dye. However, it is also a significant source of water contaminant and a threat to the environment and human health. In this white paper, learn about an optimal method to extract methylene blue employing the NanoPak-C graphite microbead SPE columns. Further, we share a protocol to quantify mL and larger volumes of methylene blue using a using a visible spectrophotometer.
