Analytical Methods for the Determination of Hesvy Metals in Textile Industry

Heavy metals in textile waste water represent a big environmental problem, and are a potential danger to human health when present on textiles. Furthermore the presence of some metals influences the production of textiles. Heavy metals are often used as oxidizing agents, as metal complex dyes, dye stripping agents, fastness improvers, and finishers. Thus they act as hazardous sources throughout entire textile processing. Toxic effects of heavy metals in men are well documented. Therefore it is important to monitor heavy metals throughout the entire production. Today maximum permissible values for metals in textiles are given by different regulations. According to them heavy metals have to be determined both qualitatively and quantitatively. Several analytical procedures for the determination of heavy metals were tested for their application on textiles. The advantages and disadvantages of TLC, UV-VIS, GF-AAS, ICP-OES, and ICP-MS methods espectively are discussed.
