Adsorption Mechanism of Lead on Wood/Nano-Manganese Oxide Composite
Discharge of untreated industrial wastewater containing heavy metals such as Pb2+ is hazardous to the environment due to their high toxicity. This study reports on the adsorption, desorption, and kinetic study on Pb2+ removal from aqueous solutions using wood/Nano-manganese oxide composite (WB-NMO). The optimum pH, contact time and temperature for adsorption were found...
متن کاملInfluence of humic acid applications on soil physicochemical properties
7 Soil structure is often said to be the key to soil productivity since a fertile soil, with desirable 8 soil structure and adequate moisture supply, constitutes a productive soil. Soil structure 9 influences soil water movement and retention, erosion, crusting, nutrient recycling, root 10 penetration and crop yield. The objective of this work is to study, humic acid (HA) 11 application on some...
متن کاملCOMPARISON OF MICROBIAL HUMIC ACID PRODUCED BY Aspergillus niger X1 AND SOIL HUMIC ACID
A comparison is drawn between fungal humic acid produced by Aspergillus niger X1 and soil humic acid regarding elementary and functional groups analysis. Elementary and functional groups analysis show that unhydrolyzed fungal humic acid contained more H and N per unit weight, more alcoholic OH but lower CO2H and phenolic OH groups than unhydrolyzed soil humic acids. The C and N content of 6(N) ...
متن کاملAdsorption and desorption of lead in Iranian acid and alkaline soils amended with sewage sludge-derived biochar
The effective management of sewage sludge materials in an environmentally and economically acceptable way is through the pyrolytic conversion of the sludge to biochar and its use for agricultural purposes. The aims of this work were: (1) to assess the effect of biochar prepared from sewage sludge at two different temperatures (350 ºC and 650 ºC) on the adsorption/desorptio...
