The threat of water pollution to the environment has aroused widespread concern.
Thus, this innovation highlights the development of efficient adsorbents to treat
contaminants such as dyes, food colouring and heavy metals. VersaBent 2.0 was made
from natural resources of polysaccharide and biomass which proposed as green
chemistry strategy for the environment. VersaBent 2.0 was prepared by immobilizing
yeast into the matrix of sodium alginate beads. Beads was upgraded using PVA (polyvinyl
alcohol) synthetic polymer which is cheap and non-toxic that will be added to produce
strong and durable beads Then, the VersaBent can be used to remove the target
contaminants via adsorption process. This innovation product also has a high
commercialization potential due to low-cost of raw material and production.
Key words: dye, food colouring, textile, adsorption, biopolymer
