Abstract
The study was conducted to determine the heavy metals concentration in ten batik
textile industries located in several areas around Pantai Cahaya Bulan (Kelantan) and
compared to the permissible limit of heavy metals that allowed by Environmental Quality
(Sewage & Industrial Effluent) Regulation 1979. the heavy metals analysis was conducted by
using graphite furnace-atomic absorption spectroscopy (GFAAS}. The samples collection was
conducted at 0 m discharge point in order to get the maximum heavy metal contents in batik
industry effluent. The results of this study show that concentration of total Lead (Pb},
Cadmium (Cd). Manganese (Mn) and Nickel (Ni) ranged from 3.06±0.0012 to 48.5±0.0193,
0.023±0.0029 to 0.677±0.065, 0.344±0.0084 to 20±0.0170 and 0.335±0.0045 to
1 l.61±0.0082μg/L, respectively. The concentrations of free heavy metals of Pb, Cd, Mn and
Ni ranged from 4.78±0.0017 to 43.3±0.0085, 0.0107±0.001 to 0.064±0.0023, 0.01±0.0016 to
16±0.0410 and 0.003±0.0001 to 0.462±0.0057μg/L, respectively. The results of total heavy
metals concentration and free heavy metals concentration in this study below the limit set by
the Environmental Quality (Sewage & Industrial Effluent) Regulation 1979.
