Harnessing a carbon-based material from food waste digestate for dye adsorption: the role of hydrogel beads in enhancing the material stability and regenerative capacity

Abstract

This study has been focused on both the ecologic and the economic gains resulting from the food waste treatment. Accordingly, anaerobic digestion and adsorption were combined to solve these problems,...

Recent advances in nano-fertilizers: synthesis, crop yield impact, and economic analysis

“…25 Groundwater can be contaminated by chemical fertilizers containing nitrogen, phosphate, and potassium. 26,27 Nitrate-based fertilizers are responsible for methemoglobinemia, which can damage the respiratory and circulatory systems. Studies have shown the impact of chemical fertilizers on water, soil, and air pollution.…”

Novel chemically reduced cobalt-doped g-C3N4 (CoCN-x) as a highly heterogeneous catalyst for the super-degradation of organic dyes via peroxymonosulfate activation

“…The role of initial pH in practical applications is crucial to the degradation of organic pollutants. To this end, various pH tests in a range of (3)(4)(5)(6)(7)(8)(9)(10)(11) were conducted on the CoCN-NaBH 4 /PMS system, as depicted in Fig. 9d.…”

“…Undoubtedly, the issue of organic dye pollution is becoming an increasing environmental hazard. [1][2][3] Such pollution results from the intensive development of chemical industries, which is the primary culprit behind the environmental degradation by organic dye pollutants. [4][5][6][7][8] In the last few years, numerous scientific papers have been published with the aim of finding solutions to this environmental contamination problem.…”

Efficient degradation of orange G dye using the quartz-sand@polythiophene composite for peroxymonosulfate activation: a sustainable approach for advanced oxidation processes

“…Synthetic dyes released from industrial activities pose a threat to both aquatic ecosystems and human health. 1,2 Consequently, the development of effective and sustainable strategies for the removal of these contaminants is of paramount importance. [3][4][5][6] Peroxymonosulfate based advanced oxidation processes (AOPs) have emerged as a promising technique for the degradation of organic contaminants due to the versatility, longer half-life (t 1/2 = 30-40 ms), and strong oxidizing potential (2.5-3.1 V) of sulfate radicals.…”
