Textile modified with methyltrioctylammonium thiosalicylate ionic liquid was successfully used for Magnetic textile solid phase extraction of copper ions. After extraction process the modified textile changed color to gray and black. The textile photos were employed for image analysis using HSB and RGB color spaces. It was shown that values of saturation (S) and red channel values (R) were proportional to the copper ions concentration in the analyzed samples, the value of saturation was almost linearly proportional to copper ions concentration in the range 10−3 – 10−5 mol L−1. This inexpensive, simple and elution free assay has a potential to be a useful alternative to existing semiquantitative determination procedures for copper ions analysis.
