Use of Heavy Metals in Textile Wet Processing
ثبت نشده
چکیده
The currently recommended concentrations of aftertreatments containing heavy metals often prevent a textile finisher from meeting effluent discharge regulations. This study involved optimizing the application procedures and concentrations of copper sulfate for copperizing direct dyes on cotton and of tartar emetic (potassium antimony tartrate) for insolubulizing tannic acid on dyed nylon. The results of lowered concentrations and alternative application methods show the possibility of reducing effluent while maintaining ?he colorfastness qualities of textiles.

Analytical Methods for the Determination of Heavy Metals in the Textile Industry
Heavy metals in textile wastewater represent a major 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 through...

Backgrounds and Objectives : Heavy metals in dust can enter to the human body through ingestion andinhalation. They can pollute the water and soil resources via atmospheric precipitation and accumulate in the plants tissue and enter human body by water and food. The aim of this study was measurement of the heavy metals in wet and dry atmospheric precipitation and effects of pollution sources at...
متن کاملHeavy Metals in Neuston from the Straits of Malacca
Heavy metals cadmium, lead, copper and zinc in neuston were analyzed from samples collected with a modified neuston net (310 μm mesh size) during an oceanographic cruise from July 29 to August 8, 2000 in the Straits of Malacca. The period of sampling coincided with South-West (SW) monsoon. The heavy metal concentrations in neuston were relatively low: ranging from 1.19-1013.70 μg g-1 wet weight...

Textile wastewater contains substantial pollution loads in terms of Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Total Suspended Solids (TSS), Total Dissolved Solids (TDS) and heavy metals. Phytoremediation used for removing heavy metals and other pollutants by aquatic macrophytes treatment systems (AMATS) is well established environmental protective technique. A lab scale stud...
