18 Jun Use of Nanoparticles for Removal of Heavy Metals from Waste Water
अपशिष्ट जल से भारी धातुओं को हटाने के लिए नैनोकणों का उपयोग Heavy metals are some of the most serious environmental pollutants, particularly in water and soil. Heavy metal pollution poses a risk to the environment, and it can be detrimental to human health via the food chain. Thus, it is very important to determine effective methods for remediating heavy metal contamination. Heavy metals in wastewater can have detrimental effects on all forms of life when discharged directly into the environment. The introduction of heavy metals into water is a growing and serious environmental and public health concern because of the toxicity of heavy metals and their non-biodegradable nature. Many technologies have been developed for removing toxic heavy metals from wastewater. Methods used to remove heavy metals from wastewater include reduction and precipitation, coagulation and flotation, adsorption, ion exchange, membrane technology, and electrolysis.These methods are generally expensive or ineffective, particularly when the metal concentrationexceeds 100 ppm. Adsorption is currently considered the best method for wastewater treatment because it is inexpensive, widely applicable, and efficient, and it generates relatively low amounts of sludge. There is growing emphasis on using alternative low-cost unconventional materials as sorbents in the removal of heavy metals. A number of inorganic and organic adsorbents have been suggested for use in adsorption methods,...
