A COMPARATIVE ANALYSIS ON MN (VII) REMOVAL FROM WASTEWATER USING LEAVES OF DALBERGIA SISSOO AND BRASSICA CAMPESTRIS BY BIOSORPTION METHODAbhishek Solanki, Hanuman, Bharat Singh and Vikal GuptaAbstract An investigation has been carried out to discover the simplest and most affordable method for Mn (VII) removal using adsorbents like the leaves of Dalbergia sissoo and Brassica campestris plants. In some areas of Rajasthan, these plants are widely distributed and their leaves are present as bio-waste. These leaves can be utilised for the treatment of industrial wastewaters. Numerous hazardous metals are present in industrial effluents, which are harmful to the soil, plants, trees, and other vegetation. The heavy and toxic metal ions can create bad impact on human health. In this study, we focus on removing Mn (VII) by implementing a biosorption approach using activated leaves of Brassica campestris and Dalbergia sissoo. With the use of the Langmuir and Freundlich isotherm models, the biological method has been evaluated. Effects of various parameters like contact time, adsorbent dosage, metal ion concentration and pH have also been studied. |
