Abstract	Test strips were proposed for the simultaneous determination of the sum of heavy metals, iron(III), copper, zinc, total alkalinity, hardness, chlorides, sulfates, nitrates, nitrites, and fluorides, and composite test strips were proposed for the determination of copper, iron(III), and cobalt. Determination is based on the dependence of the length of colored zones of indicator papers sealed in a polymer film and with one edge in contact with the test solution on the concentrations of the analytes. The analytical range is 0.1–1000 mg/L. Procedures were developed for the determination of the above components in blood serum, hair, and solutions. The relative standard deviation is no higher than 40%, and the time of analysis is 15–20 min. Two-layer and composite test plates were proposed for the simultaneous determination of mercury(II), copper, iron(III), zinc, cadmium, fluorides, and chlorides by the diameter of colored zones after the impregnation of plates with the test liquid through a hole in the film with which the indicator paper was sealed. Two-layer test plates are squares of indicator paper, which do not contact with each other and are sealed with three layers of a transparent polymer film. Composite test plates are 3 × 3-cm squares made of indicator paper triangles and sealed with a polymer film from the two sides. Analytical ranges of different components are 0.5–50 mg/L. Procedures were developed for the determination of the above elements in galvanic slimes. The relative standard deviation is no higher than 40%; the time of analysis is 2–5 min.
