An eco- friendly method to remove copper ion from drinking water by using homemade bio-adsorbent in tip-tea-bag

To remove excess copper from potable water, a point of use technique has been developed by taking the medicinal valued bio-adsorbent in a dip-tea-bag and adsorption studies were conducted in a real sample. By spiking remaining concentrations of copper was analysed using AAS. The medicinal valued ten different bio-adsorbents were prepared by grinding bark, leaves and spices and conducted adsorption studies. Among them the Azadirachta Indica (Neem) bark was chosen and carried out the experiments such as varying the quantity of bio-adsorbent, contact time and concentration of heavy metal. Present method has been found to be worth to consider as point-of-use technique because every time the bioadsorbent has been used and adsorbent material is removed easily. (C) 2019 Elsevier Ltd.
