Methylene Blue Adsorption by Novel Magnetic Chitosan Nanoadsorbent

Adsorption of Methylene Blue from Aqueous Solutions by Silk Cocoon ‎

This study concerns the performance of cocoons spun by silk worms as a natural ‎adsorbent for removal of Methylene Blue (MB) from aqueous solutions. To study the adsorption ‎process, the effect of various parameters such as contact time, adsorbent dosage, dye initial ‎concentration, and pH of the solution were investigated. According to the experiments, the kinetic ‎data were best described by ...

Quantitative adsorption of methylene blue by dead yeast cells.

Quantitative studies of dye adsorption by bacteria have been made (Kennedy and Barbaro, 1953; Barbaro and Kennedy, 1954; Kennedy and Woodhour, 1956; Barbaro et al., 1956) in order to measure the degree of gram-positiveness, and to study the influence of several factors on the quantity of dye retained by the microorganisms. No attention has been given, however, to the applicability of the physic...

Adsorption characteristics of methylene blue onto the N-succinyl-chitosan-g- polyacrylamide/attapulgite composite

−N-succinyl-chitosan-g-polyacrylamide/attapulgite (NSC-g-PAM/APT) composite was applied as adsorbent for the removal of methylene blue (MB) from aqueous solution. The initial pH value of the dye solutions, the contact temperature, the contact time and the concentration of the dye solutions on adsorption capacity of the composite for MB dye were investigated. The adsorption kinetics and isotherm...

Adsorption of Methylene Blue, Bromophenol Blue, and Coomassie Brilliant Blue by α-chitin nanoparticles

Expelling of dyestuff into water resource system causes major thread to the environment. Adsorption is the cost effective and potential method to remove the dyes from the effluents. Therefore, an attempt was made to study the adsorption of dyestuff (Methylene Blue (MB), Bromophenol Blue (BPB) and Coomassie Brilliant Blue (CBB)) by α-chitin nanoparticles (CNP) prepared from Penaeus monodon (Fabr...
