Abstract: Oil spill is a major environmental disaster that has continued to plague the petroleum industry. After the 2010 Deepwater Horizon spill, there has been an increase in research on the uses of low cost environmentally sustainable options for spill clean-up. The use of low-cost sorbents is considered a cost-effective and environmentally friendly. With over 5 million tonnes of waste chicken feathers generated annually around the globe, the management of the solid waste is an enormous challenge. In this paper, we examine the adsorptive removal of different oil types from sea water using waste chicken feathers. The adsorption properties were investigated in batch adsorption experiments using crude oil, vegetable oil and diesel fuel. The maximum adsorption capacities were 7694 mg/g, 6059 mg/g and 4097 mg/g for vegetable oil, crude oil, and diesel fuel respectively. The adsorption kinetics varied inversely with increasing temperatures and was better described by the pseudo-second-order kinetic

Abstract: The removal of endocrine disrupting chemical progesterone by adsorption onto waste black tea leaves was investigated in laboratory-scale experiments. The removal efficiency was compared with the widely used granular activated carbon (GAC). The performance of waste black tea leaves for the adsorption of progesterone was found to be comparable to conventional GAC. The maximum adsorption capacities for tea leaves and GAC were 1.8 mg/g and 1.4 mg/g respectively. The values for the thermodynamic parameters associated with sorption of progesterone onto tea leaves were Gibb’s free energy (-6.0 KJ/mol), enthalpy (-3.7 KJ/ mol) and entropy (8.0 J/mol K), indicating that the sorption process was favorable, spontaneous and involved physical adsorption held by Van der Waal forces. The adsorption was guided by diffusion within the pores of the tea leaves.
