Volume 13, Issue 1 , January 2022, , Pages 2201-1686

https://doi.org/10.5185/amlett.2022.011686

Abstract
  The present study is aimed to remove toxic crystal violet dye from aqueous solutions. In this study guar gum (GG) has been grafted with acrylic acid (AA) by following microwave assisted grafting method. Two different nanomaterials i.e., nanoclay (NC) and multiwalled carbon nanotubes (MWCNT) has been ...  Read More

Synthesis, Characterization And Mercury (II)  removal Using Poly(vinylacetate) Grafted Guar Gum
Volume 7, Issue 7 , July 2016, , Pages 573-578

https://doi.org/10.5185/amlett.2016.6006

Abstract
  Guar gum-graft-poly(vinylacetate) (GG-g-PVA) has been synthesized and evaluated for Hg(II) removal from synthetic Hg(II) solution. The optimum performance GG-g-PVA sample (G1) was synthesized using 0.25 g guar gum, 1.0 × 10 -2 M K2S2O8, 2.3 × 10-2 M ascorbic acid, 0.46 M vinyl acetate (VA), ...  Read More

Cadmium (II) Removal From Aqueous Solution Using Guar Gum-silica Nanocomposite

Vandana Singh; Somit Kumar Singh

Volume 6, Issue 7 , July 2015, , Pages 607-615

https://doi.org/10.5185/amlett.2015.5873

Abstract
  In present communication we report on Cd(II) adsorption using our recently reported material, the guar gum-silica nanocomposite. The equilibrium, thermodynamics and kinetics of Cd(II) adsorption onto composite from aqueous solution were investigated. Optimum experimental parameters were determined to ...  Read More

Diastase α-amylase immobilization on sol-gel derived guar gum-gelatin-silica nanohybrid

Vandana Singh; Devendra Singh

Volume 5, Issue 1 , January 2014, , Pages 17-23

https://doi.org/10.5185/amlett.2013.7513

Abstract
  In the present communication, we report on diastase alpha amylase immobilization at guar gum-silica nanohybrid material (H5). The immobilized amylase (H5-Amyl) showed significantly higher bioactivity (21.62 U mg -1 ) as compared to free amylase (15.59 U mg -1 ) in solution at pH 5 and temperature 40°C. ...  Read More

Guar Gum: A Versatile Industrial Plant Polymer

Hisatoshi Kobayashi

Volume 3, Issue 4 , September 2012, , Pages 265-265

https://doi.org/10.5185/amlett.2012.9001

Abstract
  Guar gum is a non-ionic carbohydrate polymer derived from the endosperm of two annual leguminous plants Cyanaposis teragonalobus and Cyanaposis psoraloides. Chemically, it is galactomannan consisting straight chain of mannose units attached by β-D-(1→4) linkages, having α-D-galactopyranosyl ...  Read More
