Wastewater from industry can lead to water pollution if untreated, especially due to its highrnconcentration of heavy metals. Heavy metals are considered extremely harmful because they canrncause illnesses, disorder and diseases to human. Therefore, industrial wastewater containing heavyrnmetal should be treated before discharge to the water stream but its treatment is very costly. Therernare several techniques to remove heavy metals from wastewater such as biosorption, filtration andrnadsorption of heavy metal but there is some limitation such as long treatment time. The adsorption ofrncopper and zinc from synthetic wastewater by lignite coal was investigated. The effect of differentrnenvironmental conditions such as contact time, initial metal ion concentration adsorbent dosage and pHrnon metal ions removal has been studied by keeping stirring at 200rpm and solution temperature ofrn25oc. Experiment results showed that maximum removal of Cupper ion by lignite coal at optimumrncondition (6 pH, 120 min. contact time, 2g adsorbent dose and 200ppm concentration) is 82.32% andrnfor Zinc ion are 77.54% at optimum condition (4 pH, 90 min. contact time and 1.5g adsorbent dose,rn150ppm concentration). These experimental studies on adsorbents would be quite useful in developingrnan appropriate technology for the removal of heavy metal ions from contaminated industrial effluents.Thernadsorption data of metal ions at temperature of 25Â°C have been described by the Freundlich andrnLangmuir isotherm models. The sorption process conformed to both Langmuir and Freundlichrnisotherms with maximum sorption capacities of 16.468 and 13.45mg/g for copper and zinc,rnrespectively. The equilibrium time was found to be of the order of 120 minute for copper and 90rnminute for zinc sorption by lignite coal. Sorption kinetics was determined using pseudo first-order,rnsecond order and, hence adsorption rate constants were calculated. The results revealed that sorptionrnkinetics of copper and zinc followed pseudo second order with regration coefficients of 0.9994 andrn0.9988 respectively. Optimum results were applied to remove copper and zinc from real electroplatingrnwastewater. Optimum parameters for copper sorption were pH=6, contact time =120 mins, and ligniterndosage of 2gm and for zinc batch sorption were; pH=4, contact time =90 minute, and lignite dosage ofrn1.5gm. The results showed lignite coal reduced copper ions from its initial concentration of 187.67rnmg/l to 38.37 mg/l while zinc was reduced from 147.45 mg/l to 88.73 mg/l. Their respective removalrnefficiency was 63.45% and 59.65%
