Removal properties of dissolved boron by glucomannan

2013-4-1  Therefore, the removal efficiencies of dissolved boron were examined using both an insoluble KGM gel and KGM semi-gel. The former did not remove dissolved boron, but the latter did. The difference in the ability of boron removal was due to the presence of diol group inside. KGM loses free diol group during the process of gelation.

Removal properties of dissolved boron by glucomannan

Highlights The boron removal efficiency was compared between the gel and semi-gel of glucomannan. The semi-gel removed the boron at pH ⩾ 11, which boron species is present as B (OH) 4-. The semi-gel retained the free diol group had a high boron removal capacity. The gel lost diol group in the gelation process was not able to remove the boron. The presence of metals did not effect to boron

Removal technology of boron dissolved in aqueous

Boron is an essential micronutrient for plants, humans and animals, which is also an important component used in various industries. Along with the wide spread of boron application, more and more boron waste pollutes the drinking water sources, and leads to a series of environment and health problems.

Removal of boron dissolved in water Kluczka 2007

The removal of boron from water was carried out in static and dynamic systems. Isotherms for boron adsorption from model aqueous solutions on various adsorbents were applied and Langmuir constants were calculated. The results indicate that the application of the impregnants increases the ability of activated carbon to adsorb boron.
