IntroductionWater, being one of the essential elements for life on Earth, has been taken for granted by humankind
KOH and H3PO4 were supplied by Merck, Malaysia while hydrochloric acid (HCl) was obtained from Accot Lab Supplies, Malaysia
Activated carbon synthesized from Duckweeds plants is capable to remove dye from the aqueous solution
Summary
Water, being one of the essential elements for life on Earth, has been taken for granted by humankind. The release of industrial discharge and domestic effluent without proper treatment to the waterway has polluted the water resources. This indicates that the clean water resources have been in dwindling trend and it has become a serious issue worldwide since water scarcity will disrupt the daily life routine and economic development. Rapid urbanization, high population growth and increased agricultural and industrial activities have further imposed stress on limited clean water resources (Wu et al 2018). World Health Organization has predicted that by 2025, half of the world’s population will be living in water-stressed areas, with the majority living in developing and underdeveloped countries (World Health Organization 2018). Without proper access to clean water, the community will be exposed to diseases such as cholera, diarrhea, typhoid and polio, which are associated with contaminated water and poor sanitation
