“…The application of animal wastes and wastewater has increased their concentrations in the aquatic environments. Both antibiotics and heavy metals are frequently detected simultaneously in ground water and surface water (Kolpin et al, 2002;Li and Zhang, 2013;Lindsey et al, 2001;Luo et al, 2011;Satapathy et al, 2009). Antibiotics can combine with heavy metals strongly and produce complex species, which makes the behaviors of both compounds more complicated.…”

“…Discharge of industrial wastewater containing both contaminants can cause the bio-accumulation in our food chain. Tetracyclines and copper were recently found in surface water and groundwater [3][4][5][6][7]. The simultaneous presence of both has significantly negative environmental impacts.…”

a b s t r a c tSorption of tetracycline and copper onto chitosan is systematically investigated in this study. The sorption of tetracycline and copper occurs rapidly in the first few hours and 90% of completed uptake occurs in the first 11-12 and 6 h, respectively. The sorption equilibrium of both contaminants is established in 24 h. The solution pH largely affects the sorption of both contaminants. The tetracycline uptake increases as pH is increased from 2.8 to 5.6, and 2.5 to 7 in the absence and the presence of copper, respectively. The presence of copper significantly improves the tetracycline adsorption likely due to the formation of cationic bridging of copper between tetracycline and chitosan. The maximum adsorption capacity and the adsorption affinity constant for tetracycline dramatically increase from 53.82 to 93.04 mmol kg À1 and from 1.22 to 10.20 L mmol À1 as the copper concentration is increased from 0 to 0.5 mmol L À1. The uptake of copper increases with an increase in pH from around 3.5-6.0 in the absence and the presence of tetracycline. The presence of tetracycline decreases the copper adsorption, which may be ascribed to the competition of tetracycline with copper ions for the adsorption sites at the chitosan surface. The adsorption isothermal data of both tetracycline and copper are fit well by the Langmuir equation. The maximum adsorption capacity and adsorption affinity constant of copper ions decrease from 1856.06 to 1486.20 mmol kg À1 and from 1.80 to 1.68 L mmol À1 in the absence and the presence of tetracycline. FTIR and XPS studies reveal that amino, hydroxyl, and ether groups in the chitosan are involved in the adsorption of tetracycline and copper.

“…On comparison of standard deviation (SD) values as presented in Table 2, for the results obtained by both these methods, it was observed that there was significant difference in SD values by both these methods (0.91 for ICP and 1.20 for test kit). (Satapathy, 2009) Groundwater iron concentration results obtained by these methods showed that (Table 2) Figure 2, it can be observed that 28 (77.77%) water samples had iron concentration difference between the results obtained by these two methods in the range of ±0.2 mg/L. This difference (±0.2 mg/L) for the results of iron concentrations was observed at lower iron concentration (between 0.0 to 1.0 mg/L of Fe).…”

Abstract.Water is an indispensible part of human life. Groundwater is contributing significantly as a source of drinking, cooking and domestic purposes. Groundwater contains different heavy metals and iron is one of the dominating one. Chronic exposure of iron through groundwater consumption above WHO drinking water standard of 0.3 mg/L has well understood. To ascertain the impacts of groundwater iron on human health its accurate measurement is an essential aspect.
