Abstract: The presence of dyes in effluents is a major concern due to their adverse effects to many forms of life. Dyes are generally removed by conventional sorbents. This article discusses the use of adsorbents from the waste metal production (low-cost sorbents), red mud (RM) and black nickel mud (BNM), to remove methylene blue solution (MB) under different test conditions, such as time and temperature of sorption and weight of sorbent samples. From the obtained data, we can claim that the highest achieved sorption efficiency was achieved by a RM sorbent at 60 °C after 48 hours of sorption with all three weights of samples (83.01 – 83.72%).
