Abstract
This study examined the characteristics and dyeing fastness of sheep skins that had been tanned with two different vegetal tannins: hydrolysable tara and condensed quebracho tannins. After tanning, chitosan formate was applied to the leathers in four different proportions. The dye exhaustion and tensile strengths of the leathers increased as the proportion of chitosan formate increased, and the highest levels of both dye exhaustion and tensile strength were obtained in an application at a proportion of 200% on the basis of leather weight. Leathers treated with chitosan formate had slightly higher tensile strength values than the control leathers. In addition, chitosan formate was found to improve waste water parameters such as chemical oxygen demand, total suspended solids, total dissolved solids, salinity, and electrical conductivity.
期刊介绍：
Cessation. Ekoloji is an international journal that focuses on papers that report results from original research on all disciplines engaged in the field of environmental research. We welcome articles that cover the entire spectrum of environmental problems and environmental pollutants, whether chemical, biological or physical. Its coverage extends to all environmentally related issues: air and water pollution, solid waste, noise, recycling, natural resources, ecology and environmental protection. It includes articles on basic and applied environmental pollution research, including environmental engineering and environmental health. All types of pollution are covered, including atmospheric pollutants, detergents, fertilizers, industrial effluents, metals, mining wastes, oil, pesticides, plastics, radioactive materials and sewage. It also includes research papers on ecological and environmental issues such as climate change, biodiversity. The primary criteria for publication are scientific quality and ecological/environmental significance.
The journal will be read and contributed to by biologists, applied ecologists, environmental scientists, natural resource specialists, environmental engineers, environmental health specialists, agro-ecologists, veterinaries, agricultural engineers, landscape planners and designers. The journal welcomes full "research papers" and short "research notes", only in the English language.
