Recent Advances in the Treatment of Industrial Wastewater from Different Celluloses in Continuous Systems

“…Table 4 shows a summary of the investigations. Rice bran Cr (VI) 0.76 7.3 [92] MXene and chitosan Cr (VI) 0.66 5.9 [89] Chitosan-modified magnetic carbon Cr (VI) 0.3 3.8 [85] Carboxymethylated Cellulose Pb (II) 1 14 [82] Cellulose/chitosan aerogel Cr (VI) 0.9 11 [83] Cellulose aerogels Cu (II) 1. 2 12 In the references of [20,86], ideal treatment yields were obtained, adjusting 11 and 10 L, respectively.…”

“…The incorporation of titanium oxide (TIO 2 ) increases the active sites in the biomass, such as hydroxyl groups (OH) and sites where heavy metals will lodge through cation exchange [89]. EDTA is a chemical agent that enhances the adsorption process of contaminants and is used as a chelating agent in industrial processes due to its high capacity to attract heavy metals through cation exchange [91][92][93]. Table 5 shows the intraparticle constants together with their isotherms.…”

ZIF-67-modified magnetic nanoparticles for extraction of phenoxy carboxylic acid herbicides

“…3 PCAs are widely used in agricultural production due to the advantages of low cost and significant weed control effect. 4 However, most PCAs are difficult to degrade and easily accumulate in soil, water, and crops; thus, they not only pollute the environment but also pose potential threats to human health through the food chain. 1 Therefore, accurate detection of PCAs in various matrixes is important.…”
