Sustainable approaches for removing Rhodamine B dye using agricultural waste adsorbents: A review

Removal of anionic and cationic dyes using porous copolymer networks made from a Sonogashira cross‐coupling reaction of diethynyl iron (II) clathrochelate with various arylamines

“…Recyclability tests with CR and MO disclosed a 100% adsorption efficiency for three successive cycles before the uptake dropped to 73% and 82%, respectively (Figures S24–S27). It is noteworthy that, to the best of our knowledge, these results are either superior or equivalent to the adsorption capacities for several compounds ranging from polymers to composites reported in the literature 1,17,44–51 …”

A porous graphitic biochar wrapped Co9S8 core–shell composite enables pH-universal activation of peroxymonosulfate for highly efficient and rapid antibiotics degradation

“…Herein, a graphite biochar wrapped Co 9 S 8 core-shell composite (Co 9 S 8 @N-O-BC) with abundant mesopores was successfully prepared and applied to activate PMS to degrade SMX. Optimization studies revealed that the superior catalyst was synthesized at the 0.1 : 1 prepared mass ratio of Co to biochar at 800 °C calcination temperature, achieving completely degraded 20 mg L −1 SMX within 4 min in a wide initial pH range (3)(4)(5)(6)(7)(8)(9)(10)(11). Notably, the removal rate could still reach more than 60% within 30 min even under extremely acidic or alkaline conditions.…”

“…2 Lately, they have been frequently detected in real water and are highly likely to pose a threat to aquatic organisms and human health. Although there are various approaches for the treatment of antibiotics, such as adsorption, 3 membrane separation, 4 photocatalysis, 5 biological degradation, 6 etc., they still suffer from strict reaction conditions and/or high energy consumption. In this regard, highly effective methods for remediation and treatment of antibiotics pollution are still one of the major objectives of exploration.…”

Invasive plants as biosorbents for environmental remediation: a review

“…It is still controversial whether Rhodamine B is a carcinogenic and neurotoxic agent to human health (Al-Buriahi et al 2022). Although many countries ban the use of Rhodamine B as textile colorant, it is prevalently present in most water sources because of the illegal utilization (Al-Gheethi et al 2022). As a result, Rhodamine B seriously affects the water quality and photosynthesis of aquatic creatures (Bhat et al 2020).…”
