Investigation on the removal of formic acid (FOA) by adsorption on flyash-wood carbon (FA-WC) blends has been made under batch mode. The adsorption data on the variation of (i) initial concentration of acid, (ii) contact time (iii) does and (iv) particle size of FA-WC are determined.
This article describes biotechnological modes, updated in terms of environmental remediation while exploiting natural resources. Modern biotechnology embraces not only the principles of using various organisms but also the techniques of doing so. Both the aspects are dealt with in detail.
This study presents degradation of textile azo dye by newly developed photo catalyst (methylene blue immobilized resin dowex-11; particle size, 20-50 mesh), which is a cheap and a very good alternative to traditional technologies for industrial application. Activity of catalyst remains unaffected on continuous use.
