Adsorption of Brilliant Red 2BE dye from water solutions by a chemically modified sugarcane bagasse lignin

Production of carboxymethylated lignin and its application as a dispersant

“…Da Silva modified lignin obtained from the acid hydrolysis of sugarcane bagasse to prepare CML, which was used as an adsorbent for the removal of brilliant RED 2BE from effluent of the textile industry [15]. Additionally, alkali lignin from wheat straw was modified using monochloroacetic acid in order to prepare CML, which was applied as a dispersant in graphite aqueous suspensions [16].…”

Adsorption of Methylene Blue from Aqueous Solution Using Steam-Activated Carbon Produced from <i>Lantana camara</i> Stem

“…As a result, there has been a great interest in developing new adsorbent materials with diverse compositions, properties and functionalities. Although commercial activated carbon is the most widely used adsorbent for dye removal, it is too expensive [9]; consequently, numerous low-cost alternative adsorbents have been proposed including chemically modified sugarcane bagasse lignin [10], pistachio hull waste [11], coffee husk-based activated carbon [12], pine cone [13], rice husk [14], synthetic calcium phosphates [15], natural untreated clay [16], pillared clays [17], and swelling clays [18].…”

Biorefinery lignosulfonates as a dispersant for coal water slurry

“…The peak at 1421 cm −1 confirms the presence of COO-group [22]. The bands at 1190 and 1037 cm −1 are from asymmetric and S=O stretching vibration of SO 3 2− [23], respectively.…”
