Abstract: Background & Aims of the Study: Textile dyes generally are made of synthetic, organic, and aromatic compounds that may be contain of some heavy metals in their structure. Complex structure and presence of these metals cause toxicity and may be mutagen, teratogen or carcinogen. This study has investigated the ability of peanut shell powder to removal of some reactive dyes (Green 19...

It is felt very essential to develop a knowledge base on dye chemistry and effects of dyeing process variables as well as rate of dyeing and chemical kinetics of dyeing for different natural dyes and fibres combinations to manipulate the processes of natural dyeing efficiently in order to get maximum color yield in economical way. A review on the effects of dye extraction medium, optimum concen...

Corresponding author: Małgorzata MOŚCIPAN – Ph.D., e-mail: [email protected] textiles Information on the earliest textiles date back to Neolithic period (about 5000 BC) and theirs examples, mainly in the form of ancient people relicts have been found in Africa and Peru. However, the form of textiles at that time differed form that contemporary one. At the beginning grasses, creepers, branc...

Following the first report on dye-sensitized solar cells (DSCs) by Prof. Grätzel in 1991, thousands of papers have been published with the aim of making DSCs commercially viable (Fig. 1). They are attractive because of their low-cost materials and convenient fabrication by a non-vacuum, high-speed printing process. One of the key materials in DSCs is the sensitizer dye. Ruthenium-complex dyes a...
