[15-17] or ammonia [18]. Only a few researches investigated simultaneous removal of heavy metal and ammonia from their chelated solution. For example, SUN et al [19] studied the simultaneous removal...

Hunan Province Environmental Monitoring... River Heavy Metal Pollution Control Implementation Plan". It is found that E. coli, TN and TP are the main pollutants in the Changsha-Zhuzhou-Xiangtan section, and the pollution of heavy metal......
to evaluate the comprehensive pollution of heavy metals. The results show that the vertical distributions of heavy metals are different. The heavy metal concentration in the reclamation soil is lower but it is still higher than the soil background value. The heavy metal concentration in the interface between the soil and tailings is the highest, the pollution degree is the strongest. The pollution......
a struvite-based material in-situ synthesized by solution method for the adsorption of heavy metal from wastewater. Struvite is a phosphate mineral with formula of NH4MgPO4·6H2O. It is a mineral... to remove ammonia from solution, which was superior than biological method considering the heavy metal inhibition to the microbial activity [20–22]. But surprisingly it was found that the heavy metals......
