Abstract
Living in an age where water is getting scarcer by the day, and different types of pollutants are increasing, effective methods to treat this polluted water and rendering them useful again is one of the most important goals of environmental engineering. In this review paper we deal with the adsorptive properties of ink in treating waste water and thus discuss what work has been studied in similar fields by experts all around the world. This review paper also consists of discussion on what further work can be carried out to yield positive results and what is the course of action that needs to be followed for improving the current methodology of waste water treatment. Subsequently an attempt has been made for the use of ink and its related properties which can be used as a preferential adsorbent to leach out the pollutants as they get adsorbed on the ink granules. The theme of this paper is to discuss and find the ways to utilize the waste powder ink of computer cartridge, which is produced in tons over the world and thus, obtain "best results out of waste". Physical factors associated with ink and its adsorption parameters are included in this thorough study. The mechanism and kinetics of adsorption of pollutants on ink granules depend on the chemical nature of the materials and various physico-chemical experimental conditions such as solution pH, initial dye concentration, adsorbent dosage, and temperature of the system. The properties of various components of ink such as polyester, dye etc. will also play a role in adsorption of pollutants from water rendering it clean.
