MG adsorption efficiency (%) of the GO–ZnO nanohybrid in various real water matrices: distilled water, mineral water, tap water, river water, and industrial wastewater. All experiments were conducted under optimized conditions (MG concentration = 25.0 mg L−1, pH = 9.0, adsorbent dosage = 18.0 mg, temperature = 25.0 °C, contact time = 12.0 min). Error bars represent the standard deviation (n = 3).
