Hypothesis

If cellulose is the main component in biomass that play a key role in water remediation, chemically modified grass will have the same adsorption ability as chemically modified sugarcane bagasse.

During alkali pre-treatment, the presence of lone pair in OH- caused a dative bond to form between OH- and H in cellulose’s –OH group. This dative bond causes hydrogen to give out its electron to oxygen, forming  –O- to bind to heavy metal ions present in the wastewater. Since cellulose are present in grass and sugarcane bagasse, alkali pre-treatment of grass will have the same effect as pre-treated sugarcane bagasse.
