Sawdust-biomass based materials for sequestration of organic and inorganic pollutants and potential for engineering applications

Modified Polymeric Biosorbents from Rumex acetosella for the Removal of Heavy Metals in Wastewater

“…On the other hand, of particular interest were the fiber contents, which presented a significant difference ( p < 0.05), which in the case of the dry stem had a higher value (62.28%). That is why it was decided to obtain the biosorbents from this fraction of the plant, rich in cellulose, hemicellulose, and lignin, which are essential in the adsorption of heavy metals [ 34 , 35 , 36 , 37 , 38 ].…”

“…Significant differences were observed in most cases ( p > 0.05). The presence of adequate amounts of carbon is essential in heavy metal biosorption processes [ 49 ], since they are associated with the presence of lignocellulosic polymeric compounds such as cellulose, hemicellulose and lignin [ 34 ].…”

Adsorptive removal of antibiotic pollutants from wastewater using biomass/biochar-based adsorbents

“…76 This study removed cexime (CFX) from aqueous solutions using biochar made from pinecones. pH (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12), contact length (0-120 min), initial CFX concentration (10, 50, and 100 mg L −1 ), adsorbent dosage (0.1-2.5 g L −1 ), and temperature (10 °C to 50 °C) were all investigated. The dry raw material was placed in a stainless steel reactor for carbonization and heated at 20 °C per minute in an electrical furnace for 2 hours at 460 °C.…”

“…This would also assist in determining whether or not such successful experiments and inquiries also constitute a risk to the environment. (6) The majority of the literature reviews were conducted in a synthetic aqueous environment, which might restrict the potential of sorption processes owing to matrix effect(s) that can interfere with sorption in real-world practical systems. As a result, real-world applications and thorough assessments of potential impact interference on the sorption processes are necessary.…”

“…According to a recent study, India has been the world's most substantial end-user since 2015, posing a serious threat to their resistance. [4][5][6][7][8] Antibiotics can be detected in water samples due to ineffective conventional methods of elimination from wastewater. 9,10 However, some metabolized antibiotics are eliminated through defecation while the active nonbiodegradable residues accumulate greatly, developing bacteria with antibiotic-resistance.…”
