Optical detection of Rhodamine B by Pt(II) tetra-(4-allyloxy-phenyl)-porphyrin
Rhodamine B is a red, water-soluble synthetic dye with multiple uses in cosmetics, textiles, medicines, food, plastics. Nevertheless, the colorant is toxic causing irritation of the skin, eyes, and airways. For this reason, the control of foods and cosmetics is a must. The present study reports a si...

| Tartalmi kivonat: | Rhodamine B is a red, water-soluble synthetic dye with multiple uses in cosmetics, textiles, medicines, food, plastics. Nevertheless, the colorant is toxic causing irritation of the skin, eyes, and airways. For this reason, the control of foods and cosmetics is a must. The present study reports a simple and fast UV-vis spectrophotometric method for the detection of rhodamine B by using as sensitive material Pt(II)-tetra-(4-allyloxy-phenyl)-porphyrin. The method is viable in the range of rhodamine B concentrations from 1.94 x10-6M to 4.26 x10- 5M with very good accuracy. |
