It is necessary to use adsorbents derived from natural materials, such as biosorbents since they do not any damage to the environment, for pollutants elimination that contaminate the aquatic environment. Since the deficiency in the literature was determined in the study in which only the adsorbent obtained from tomato stem was used before this study, a waste material with tomato stem was selected as a natural adsorbent without chemical compounds. Phosphate and dye contaminants, which are often present in industrial and municipal wastewater, were eliminated by adsorption process. Fourier transform infrared (FTIR), x‐ray fluorescence (XRF), Zeta potential, and scanning electron microscope (SEM) with energy dispersive x‐ray (EDX) spectroscopy were used to analyze tomato stems. The tomato stems resulted in high pollutants removal efficiencies recording 99.31% of phosphate () removal efficiency and 99.44% of Direct Orange 46 (DO 46) dye removal efficiency at optimal conditions. The best conditions for phosphate adsorption were pH = 6.0, 2.0 g/L of tomato stems concentration, 50 mg/L initial phosphate concentration and a contact time of 120 min resulting in an adsorption capacity of 4.24 mg/g. The best conditions for DO 46 adsorption were pH = 12, 2.0 g/L of adsorbent concentration, initial dye of 200 mg/L concentration and a contact time of 120 min (q = 13.76 mg/g). For both adsorption experiments, the adsorbent size was chosen to be less than 500 μm. As a result of the adsorption experiments on tomato stem ash, Freundlich isotherm (R2: 0.94) was suitable for DO 46 dye adsorption and Temkin isotherm (R2: 0.99) was suitable for elimination. The phosphate (R2: 0.97) and dye (R2: 1) adsorption onto tomato stem ash was explained using a pseudo‐second‐order kinetic model. It has been determined that the adsorption of the DO 46 dye with the tomato stem ash is an exothermic (∆H: −3.174) process that occurs naturally due to its nature (∆G: −8.41). On the other hand, it was determined that the adsorption of was spontaneous (∆G: −5.21) and endothermic (∆H: 5.7357). According to the adsorption results obtained in this study, it is appropriate to use the tomato stem, which is generated as waste, as an adsorbent. It is thought that obtaining from bio‐based waste in the removal of pollutants such as dye and phosphate in water will both reduce the cost and create an advantage in terms of biodegradability.

Waste motor oil (WMO), which has no stable form or structure, causes major environmental problems and damage to the ecosystem once it is disposed to the environment. Because of the high toxicity of contents in such effluent, it must be treated before being discharged into the receiving environment. In recent years, the valorization and the use of waste materials to remove toxic pollutants is of great importance to researchers and diverse industries. In this study, the usability of waste welding powder (WWP) as an adsorbent for waste oil removal was investigated. For this purpose, investigating the usability of material, which is generated as industrial waste, in wastewater treatment will lead to the evaluation of waste. The effects of temperature, pH, WWP amount, and initial WMO amount were investigated. According to the adsorption studies, 1 g WWP/L of the processed adsorbent was able to effectively remove 95.05% of WMO (100 mg) at a pH of 2 at 30°C. Stereo microscopy images showed a large amount of oil adsorbed on the WWP surface. The different WWP properties were determined by adsorption isotherm (Harkins–Jura), kinetic (pseudo‐second order), and thermodynamic (ΔG: −5.1 kJ mol–1) experiments. It is thought that WWP, which is a low‐cost and waste material, can be used as a promising adsorbent in WMO removal.

The marble dust as a harmful industrial waste of marble fabrication was evaluated as aneconomical and efficient green adsorbent for Acid Red-1 dye and lead ions. The XRD, XRF, particle size, surface area and zeta-potential measurements were used to characterize the marble dust. The removal efficiency was optimized by studying several parameters such as pH, temperature, contact time, adsorbent dose and initial concentration. The optimum removal was achieved at pH 6, 20C after 60 min in the presence of 2.5g/L marble dust. The rates of adsorption were found to follow the pseudo-second-order model. The results showed better fitting to Freundlich isotherm. The thermodynamic studies revealed that the adsorption process is spontaneous, exothermic and favorable at low temperature. The free energy (∆G°), enthalpy (∆H°), and entropy (∆S°) changes were calculated to predict the nature of adsorption.The removal efficiency was improved by calcination of the marble at 700C. Application for textilewastewater showed high removal efficiency up to 99.9%of inorganic and organic pollutants. The product of treatment was used in the concrete and bricks manufactured, so there is nogeneration of second-order pollutants.
