Porous microwave irradiated activated carbon has been developed and its application for time efficient ultrasonic treatment of Congo‐red (CR) dye. The maximum removal efficiency of 97.73% was obtained using developed adsorbent with ultrasound treatment. The optimum parameters for maximum dye removal were obtained that is, contact time of 2 hr, adsorbent dose of 0.2 g, neutral pH, room temperature, and initial CR‐effluent concentration of 10 mg/l. Adsorption isotherms models, kinetics of the process, and thermodynamic analysis have been evaluated to investigate the adsorption performance. The pseudo second order rate kinetics (R2 = 0.99) and Langmuir equilibrium isotherm (R2 = 0.99) were well fitted to the experimental data. It has been found that microwave synthesized method was better technique in terms of energy savings, and ultrasonic treatment approach was efficient technique in terms of operational time. The combination of microwave‐ultrasonic reported to have an adsorptive capacity of 75.75 mg/g with least energy‐cost consuming approach.

In an era of increasing environmental awareness, it is very important to work towards eliminating or at least reducing as many harmful industrial substances as possible. However, the implementation of green chemistry methods for wastewater treatment can be difficult especially due to complexity, the high cost of reagents, and the required long process time. This paper focuses on using waste iron (WI) to remove two kinds of amaranth dye commonly used in industry. To enhance the process, UV irradiation and hydrogen peroxide were used. The novelty of the research was the use of efficient and reusable WI as a heterogeneous catalyst in the process. WI material characteristics was done before and after the process using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and X-ray fluorescence (XRF). Zeta potential, size characterization, circularity, and direct band gap were also determined. As a result of treatment complete decolorization of both dyes was achieved, as well as 99% absorbance removal after 15-min process time. The total organic carbon (TOC) decrease after 60-min process time was in the range from 86.6 to 89.8%. Modified pseudo-second-order reaction reflects obtained results of treatment efficiency. Treatment results, confirmed by WI material characterization, indicate satisfactory stability of the catalyst and good oxidation capacity.
