The removal and recovery of rosaniline and brilliant green were studied using batch and dynamic processes. The maximum sorption of these dyes (∼100%) was obtained in a pH range of 6–10 with a shaking time of 2–5 min. The sorption kinetics were best described by the pseudo-second-order model (R2 = 0.993). The variation in the sorption of rosaniline and brilliant green with temperature results in average values of ΔH and ΔG (i.e., −65.7 kJ mol−1 and −8.1 kJ mol−1, respectively). The sorption capacity of iodo-polyurethane powder (Iodo-PUP) was 106.8 and 154.4 mg g−1 for rosaniline and brilliant green, respectively. The dye removal percentage and detection limit were 99.5% and 20 ng mL−1, respectively. The isotherms exhibit good correlation (R2 = 0.9985) with a zero intercept (0.0045). Successful application was achieved for environmental samples (i.e., industrial, laundry and sewage wastewater). The average recovery and RSD were 85.2% and 4.9%, respectively.
