Abstract
Water remains one of the most important mediums for the survival of Living organisms. However, because of the human activities, it has lost its nature and becomes extremely polluted. Among various pollutants, the synthetic dyes have huge contribution for the contamination of the natural water bodies because of their vast application in food, cosmetics, pharmaceutical, textile etc. The presence of such hazardous contaminants causes cancer, kidney failure, dysfunction of brain, infertility etc. Consequently, their removal is indispensable prior to releasing them in natural water resources. Here, low cost adsorbent (activated carbon) was prepared from date palm trunk fiber by using chemical activation using H 3 PO 4 as activating agent. That was utilized for removal of basic cationic dye Malachite Green as a model dye from water by using the Batch adsorption method. The effect of different parameters including adsorbent amount, pH and contact time were studied. The optimum conditions determined were adsorbent dosage 0.5g, contact time 20 minutes and pH5-7. From the result, we conclude that activated carbon of date fiber remains an efficient adsorbent for removal of Malachite Green and may prove the best low cost adsorbent for other dye effluents and wastewater treatment.
Highlights
Water is considered very important for life due to its application in every walk of life, but due to the rapid growth of human population and rapid industrialization, water’s nature and quality has been polluted in a great extent [1]
The peak around 3450 cm-1 is due to the presence of alcoholic OH group in activated carbon; it may be the peak of carboxylate OH group and water
Low cast adsorbent, activated carbon was prepared from date trunk fiber, by using chemical activation using H3PO4 as activating agent
Summary
Water is considered very important for life due to its application in every walk of life, but due to the rapid growth of human population and rapid industrialization, water’s nature and quality has been polluted in a great extent [1]. According to the latest findings more than 100000 synthetic dyes are identified and it has been reported that globally approximately more than 0.8 million tons of dyes are annually produced [5,6,7,8] These toxic dyes become the cause of serious damage to the human health like kidney failure, damage of liver ,central nervous system ,brain ,reproductive system, hemorrhage, skin related complications etc. In this study, activated carbon was prepared from Date palm trunk fiber and was used for the adsorption of Malachite Green from water under different parameters like adsorbent concentration, pH and contact time. It was found one of the best adsorbents for this purpose
