Removal of Heavy Metals from Water

Chicken eggshells, Banana peels and Pumpkins are used as good adsorbents for removing heavy metals from contaminated water, which have been observed and studied currently. The effects of various parameters such as pH, agitation speed and contact time was studied and good results were obtained at pH 7, 100 rpm and 90 mins of contact time. The results indicate that usage of household waste such as these can be used as a good biosorbent for removal of heavy metals on a large scale and create effective, cheap and efficient methods in treating wastewat Now a day’s various toxins are released into water leading to a great deal of water pollution. Many heavy metals from various industries like battery plants, metal processing industries, pharmaceuticals, hospitals, mining fields etc. are being released into the water bodies leading to unsafe water for normal consumption. The most common heavy metals found are copper and lead, which when present in high concentrations may be very fatal to the health and the surrounding environment as well [1]. In order to obtain clean and safe water it is required that these toxic chemicals and metals should be removed.
