Abstracts
Analysis of heavy metal in dyeing wastewater obtained from the dyeing process. Determination of Cu,
Zn, Pb, Cr and Cd in dyeing wastewater obtained from dyeing process was studied by AAS. The data showed that
many samples had higher copper, zinc and lead than the standard of industrial wastewater. The consideration
eliminated heavy metal from wastewater to focus attention on identifying efficiency low-cost. absorbents and
excellent adsorption capacities for various heavy metals. The natural zeolite was applied to remove heavy metal
ions from aqueous solution. Modenite and Clinoptilolite, natural zeolite found in Songkhla province, an adsorbent
