and 4.6 indicated that, Coconut fibers have the adsorption capacity of input HM, the amount of of is better than because with the same amount of that contained in wastewater is lesser than the amount in both concentration of 500 mg/l, 1000 mg/l This results showed that coconut fibers have the highest adsorption productivity that is 84.326 % in F3 Pb ( with the HM concentration added is 500 mg/l in

the successful application in the use of sugar-cane bagasse, peanut shells and coconut fibers in the HM domestic absorption experiments with HM concentrations are given in 500 mg/l and 1000 mg/l and it provides a high efficiency, we have applied in the reality to absorb the heavy metal in the wastewater after the 32 mineral exploitation in the mining area of lead, zinc Hich village in Tan Long commune, Dong Hy district, Thai Nguyen province The application of technology to adsorpting the heavy metal after the mineral exploitation was achievedgood results 4.2.1 Assessing the heavy metal concentration that contained in wastewater in the mining area of Lead and Zinc in Hich Village in Tan Long commune, Dong Hy district, Thai Nguyen Province The mining activities in the mining area: heavy metals and other hazardous chemicals in mining area have a directly affect to the health of those exposed and cause of the diseases related to eyes, skin, nose, throat, kidney, liver disease even cancer, destroying the central of nervous system Surface water and groundwater is also seriously polluted by this activity Toxic substances and heavy metals affected to the surrounding area such as polluting the surface water, ground water and residential areas The findings of the medical institute of labor and environmental hygiene shows that the mining exploitation activities in the mining of lead, zinc in Hich village often discharge to the environment a large number of heavy metal, the heavy metal levels exceeding the allowable limit from 2-10 times of lead, 2-15 times of Zinc Table

0.5 From table 4.4, we can see that the concentration of Pb that contained in waste water after the mining exploitation in this study is very high The concentration of Pb that 33 determine in this area is 55.654 mg/l whereas the concentration of Pb in ISO is very low, just 0.5 mg/l It exceeded11.13 times compared with that in ISO These results showed that the aquatic environmental in this area was seriously pollutedby Pb concentration It has brought an enormous affect to human health and livingorganisms surrounding this area 4.2.2 Assessing the ability to absorb heavy metals (HM) in the

see that the concentration of heavy metals which extanted in the wastewater has dropped greatly Its mean that sugar-cane bagasse, peanut shells and coconut fibers absorbed a large number of heavy metal This results show that most of heavy metal extanted in water are over the standard regulation 36 PART V.DISCUSSION AND CONCLUSION 5.1.Discussion This review shows that the study on the wastewater treatment capacity after the mining exploitation by using the agricultural wastes (sugar-cane bagasse, peanut shells and coconut fibers) for heavy metal removal attracted the attention of many scientists A wide range of low-cost adsorbents obtained from chemical modified agricultural byproducts waste has been studied and the study was focused on the removal of heavy metal ions like and ions In addition, the results showed that the amount of Pb concentration whichaccumulates in the aquatic environment is very high Sugar-cane bagasse, peanut shells and coconut fibers have the different adsorption capacity corresponding with the different amount of waste-products The more amount of waste-products placed in water is the larger ability of waste-product to absorb heavy metal For sugar-cane bagasse, the highest ability to absorption of heavy metal is 900g, sugar-cane bagassecan absorbed about 61% (Formula 3, Pb, banana peels = 600g) 2.6 times higher compared with (Formula 1, Pb, banana peels = 200g) Similarly, the highest ability of peanut shells and coconut fibers to absorb of heavy metal is 900g and declining due to reducing the amount of peanut shells and coconut fibers The results shown that coconut fibers have the highest heavy metals adsorption capacity, followed by sugar-cane bagasse and peanut shells have the lowest adsorption productivity due to the structure of each agricultural by-products Because of the structure of peanut shells are very thin, its adsorption capacity of heavy metals is not well as sugar-cane bagasse and coconut fibers 37 A large amount concentration of heavy metal in water such as and has been absorbed by sugar-cane bagasse and peanut shells and coconut fibers However, the concentration of heavy metal in water is still higher than ISO 40:2011/MONRE (the standard content of heavy metal in water is Pb: 0.5 mg/l and Cu: mg/l) Therefore, we need more deeply researches to study about this case in the future 5.2 Conclusion In conclusion, results shown in the thesis clearly indicate the absorption capacity of sugar-cane bagasse, peanut shells and coconut fibers The absorption of and by using agricultural wastes was examined and analyzed After conducting the experiment, the results showed that agricultural wastes have the ability to absorb the heavy metal and in wastewater and if we conduct the experiment many times repeately, we can reduce the amount of heavy metal in wastewater to allowable limit By comparing the using of agricultural wastes like sugar-cane bagasse, peanut shells and coconut fibers for removal the heavy metal ion in the wastewater, we can use F3 (with the highest amount of agricultural by-products in both HM concentration) in order to handle and in wastewater because it have showed the best results in improving the water quality This agricultural by-products is not only applied to absorb , and , but it can also apply to remove other heavy metals like , Therefore, the study and the application of the agricultural wastes will open a new direction in improving the water resources quality 38 Need for further study about the absorption of other metal ions on the adsorption materials (sugar-cane bagasse, peanut shells and coconut fibers) in order to evaluate the absorption capacity of the absorbent materials completely and optimal 39 REFERENCES
