Zat warna indigo karmina merupakan salah satu senyawa organik yang digunakan dalam proses pewarnaan tekstil. Zat warna ini menghasilkan limbah cair yang mengakibatkan pencemaran dan kerusakan lingkungan. Sementara seng sisa juga mudah ditemukan.

Elektrodekolorisasi pewarna indigo karmina efektif dilakukan pada pH asam yaitu 4 dengan persen dekolorisasi 94,52% dan pada temperatur 70oC dengan persen dekolorisasi 98,09 %.
