“…Straight lines that pass through the origin may be due to the difference in mass transfer rate in the initial stage of adsorption. Furthermore, the intercept provides information on the thickness of the boundary layer, the larger the intercept, the greater the effect of the boundary layer [127,[136][137][138].…”

The use of antibiotics for breeding and for humans increased considerably in recent years, as a dietary supplement to enhance animal growth. This frequent use leads to the detection of residues in water and wastewater. Thus, the emergence of new strains of bacteria resistant to these antibiotics and, can lead to incurable diseases of livestock, and can lead to a possible transmission of these strains to humans. The purpose of this work is to develop new materials based on treated Maghnia clay, activated carbon, cement, and PVA polymer, named geomaterials. These materials were intended for the containment of hazardous wastes in landfills. The removal of tetracycline from aqueous solution was tested by adsorption onto synthesised geomaterials and their mineral constituents. Adsorption kinetics revealed that tetracycline was rapidly retained by GM and ATMa. This was confirmed by the relatively short equilibrium time of 30 min. The pseudo-second-order and intraparticle models well fitted the adsorption kinetic of the TC-adsorbent studied systems. It was noticed that the adsorption kinetic passes through several mechanisms, was demonstrated by the multi-linearity on the plot of qt against the square root of t. The adsorption capacity (Qa ) of TC onto GM is pH-dependent. Indeed, Qa reaches a maximum value (Qa = 12.58 mg ∙ g–1 at a very acidic pH of 2, then the adsorbed amount decreases to reach a minimum value at pH of 8, and for basic pHsQa increases up to 10 mg ∙ g–1.

“…In similar report, simultaneous graft copolymerization of acrylamide (AAm) on the Jhingan gum (JG) using CAN initiator in aqueous medium along with crosslinking by borax lead to the fabrication of JG-g-PAAm/B hydrogels which used for removal of Brilliant Blue R (RBBR) dye from water. [54] The hydrogel could regenerate by washing in aqueous medium under ultrasonic irradiation following by immersing in 0.1 NaOH alkaline medium. In the first cycle the dye removal efficiency was around 92 % which reduced to around 70 % after five cycles used-regeneration.…”

Self-healing polyol/borax hydrogels have found great applications in various areas; especially in sensors, flexible electronics and biomedical fields. In this review, fabrication and characteristics of various types of borax-based hydrogels are discussed. Mechanical properties and self-healing behaviors of these hydrogels are strongly affected by the types of polyol, ratio of polyol:borax, and concentration of each component. Incorporation of highly polar nanofillers (such as cellulose nanofibers) into hydrogels and fabrication of double-network structures have been employed as the promising strategies for improving the mechanical properties. Other additives have also been examined to generate nanocomposite hydrogels for a wide variety of uses; e. g. polyphenols for developing adhesives, conducting polymers, and hybrid structures based on carbon nanotubes and graphenes for electroconductivity, Ag and ZnO nanoparticles for antibacterial property, and quantum dots for fluorescence.

“…Remazol Brilliant Blue R (RBBR) also known as Reactive Blue 19 is an anthraquinone dye (Trivedi et al 2009). Remazol Brilliant Blue R used in the textile industry and as the starting agent for the manufacture of polymeric materials is highly toxic, carcinogenic, and hazardous to aquatic organisms (Mate and Mishra 2020) The chemical structure of the reactive dyes leads to low biodegradability and recalcitrant characteristics. Therefore, it is crucial to treat reactive dyes containing effluents before discharge to surrounding environments (Yagub et al 2014).…”

Remazol Brilliant Blue R (RBBR) is a widely used carcinogenic and toxic dye. This study focused on RBBR dye from aqueous solution using potassium permanganate, cetyltrimethylammonium bromide (CTAB) modified, and unmodified Yarrowia lipolytica biomass as biosorbent. RBBR dye biosorption studies were carried out as a function of pH, initial dye concentration, biosorbent dose, contact time, and temperature. The pH of the aqueous solution strongly influenced the biosorption percent of RBBR dye. The highest dye biosorption capacity yield was obtained at pH 2-3 as well as above pH 3, very low yield biosorption of RBBR was observed. No differences were found between chemically modified and unmodified biomass in terms of RBBR dye biosorption capacity. In the first 15 min, almost 50% RBBR dye was removed from the solution and reached equilibrium within,180 min at pH 2. Biosorption isotherm obeyed Langmuir isotherm model and pseudo-secondorder kinetic model.
