“…The pollution from dye wastewater is one of the most important environmental problems due to the fact that the use of a variety of dyes has increased [1,2]. The colour seems to be the most undesired one, as human eyes can most easily recognize it [3]. Many treatment processes have been applied for the removal of dyes from wastewater such as physical, chemical and biological treatments.…”

“…The radiation technique seems an excellent method for the preparation of hydrogels, in radiation processing technology initiator, catalyst, and cross-linker are not required because ionizing radiation is highly energetic [12]. This technique has many advantages such as easy process control and the technology is environment-friendly since it leaves no residue or pollutant in the environment [2,3].…”

The adsorption performance of acrylamide/ starch hydrogel (AAm/starch) prepared by gamma radiation for removal of direct congo red (DCR) and direct blue (DB) dyes has been investigated. The physico-chemical parameters such as dye concentration, solution pH and temperature have been studied. Favorable adsorption occurred at pH 3 for DCR and pH 10 for DB. The adsorption of dyes onto AAm/starch hydrogels was endothermic process. Experimental data have been modeled by the Freundlich isotherm. Degradation test of DCR and DB dyes using gamma irradiation in aqueous solution under various radiation doses and pH was investigated and G-value was calculated. Destruction of 70% and 75% of the dye colour solutions was succeeded at radiation dose 40 and 30 kGy for DCR and DB, respectively. Comparing the removal percent of DCR and DB dyes by radiation degradation with that done by AAm/starch hydrogel adsorption was investigated. It was found that preferring removal of DCR and DB dyes by gamma radiation degradation. The remaining concentration of dyes was followed by adsorption onto the hydrogel. Complete removal of DCR and DB was performed by gamma radiation degradation followed by AAm/starch hydrogel adsorption.

“…The adsorption of oil pollutants is one of the methods used for the treatment of oil wastewaters. Several investigations have focused on the adsorption of oil pollutants from gaseous, liquid and solid wastes employing natural adsorbents due to the suitable adsorption properties [1,[6][7][8][9][23][24][25][26][27]. Natural adsorbents used are often mineral adsorbents such as zeolite and bentonite, activated carbon, organic materials like chitosan, cotton fiber and agricultural wastes such as rice and wheat wastes, tea, coffee and coconut hysteresis, peanut wastes, shell and stems of various agricultural products, etc.…”

“…Employing natural adsorbents in the removal of oil and organic contaminants from aqueous and gaseous environments has demonstrated remarkable results [1,[6][7][8][9][23][24][25][26][27]. In this study, we examined the adsorption of hydrocarbons from the sludge of petroleum product tanks using natural adsorbents such as wheat straw, pine fruit, walnut shell, almond shell and sawdust.…”

In this study, we investigate the removal of Bemacid red dye using brewery waste in a packed bed column. We examined the effects of bed height, inlet flow, and inlet dye concentration on the column dynamics of adsorption. To assess the favorable column dynamics, we analyzed the breakthrough curves (BTCs). We also used the Clark, Thomas, Bed Depth Service Time (BDST), and Adams-Bohart models to determine the kinetic constants of the adsorption column from the obtained results of the dynamic studies curve of the BTCs. Analysis of the BTC studies revealed that both the BTCs time and worn-out time values increased with an increase in bed height and inlet Bemacid red dye dosage but decreased with an increase in the inlet flow rate. The results further showed that Thomas’ model was the most suitable for describing the entire BTCs (R2 > 0.93). Using a full factorial design to estimate the percentage effects of cited dynamic parameters, we found that these parameters accounted for 98% of the adsorption capacity. This methodology for estimation provides crucial information on the effects of parameters and the extent to which the adsorption capacity depends on the studied parameters.
