“…Still, the adsorption processes' most significant challenge is to find new and environmentally friendly adsorbents or improve the known adsorbents [8]. The well-known adsorbent used to adsorb different organic contaminants and/or dyes from wastewater are charcoal/activated charcoal [9]- [12], activated carbon [13]- [16], zeolites [17]- [19], starchbased environmentally friend adsorbent [20]- [24]. The present work aimed to convert a low cost locally available Iraqi potash ore to prepare a 13X zeolite adsorbent (13XZA), which is produced as a byproduct during potassium carbonate production via hydrothermal method.…”

The research discussed the possibility of adsorption of Brilliant Blue Dye (BBD) from wastewater using 13X zeolite adsorbent, which is considered a byproduct of the production process of potassium carbonate from Iraqi potash raw materials. The 13X zeolite adsorbent was prepared and characterized by X-ray diffraction that showed a clear match with the standard 13X zeolite. The crystallinity rate was 82.15% and the crystal zeolite size was 5.29 nm. The surface area and pore volume of the obtained 13X zeolite were estimated. The prepared 13X zeolite showed the ability to remove BBD contaminant from wastewater at concentrations 5 to 50 ppm and the removal reached 96.60% at the lower pollutant concentration. Adsorption measurements versus time showed 48.18% removal of the dye during just the first half-hour and the maximum removal closest to the removal at the equilibrium after one and half hour. Langmuir isotherm was described the adsorption equilibrium data with a maximum adsorption capacity of 93.46 mg/g and the kinetics data of the adsorption process was followed the pseudo-second-order.

“…MG is also a highly toxic triphenylmethane (TMP) teratogen and carcinogen and has been classified into the second category of dangerous goods. However, many countries continue using MG in large quantities because of its low cost and fast results [5]. Therefore, many scholars have begun to focus on the removal of MG in wastewater.…”

In this study, banana biochar (BB) and cassava biochar (CB) were roasted in a tube furnace at 400℃ for 2 h, and their adsorption effects on malachite green (MG) were studied. The removal of MG with respect to the solution concentration and reaction time was also investigated. The results show that the optimal amount of biochar is 2 g/L. Studies of the adsorption kinetics and adsorption isotherms show that the pseudo-second-order kinetics can most accurately reflect the adsorption process. Freundlich model fits the experimental data well. The theoretical saturated adsorption capacities of BB and CB are 1,092.80 mg/g and 261.42 mg/g, respectively. SEM-EDS, TGA, BET, FTIR, XRD, element analysis and other characterization techniques were used to explore the adsorption mechanism. Based on the characterization results, it is speculated that the adsorption of BB and CB for MG mainly includes chemical adsorption and physical adsorption.

“…S1 a), could be used not only in clinical treatment, but also as antimicrobial and antiparasitic agents in aquaculture to treat and prevent fungal and protozoal infections [2] . However, the United States, the European Union, China, and others have not approved the use of tpm CV in aquaculture due to it with the possible carcinogen, mutagen and teratogen effects [1] , [2] , [3] . Even so, the use of the prohibited and persistent tpm CV would be common occurance, leading to its frequent detection in aquatic environment.…”

Highlights The novel foamed-ZVI activating persulfate/chlorite by ultrasonic was applied. The real-time and online continuous detections tracked radicals transformation. The EPR spectra with different systems in different mixtures were detected. The free or non-free radicals processes induced by US were explored. The dynamics on cavitation and the US-field simulation were presented.
