Preparation for sampling various forms of phosphorus using potable water, soluble reactive phosphorus water, particulate phosphorus water, poly-phosphorous and river water were conducted to culture microorganism, and prepared total phosphorus concentration ranged between 0μg/L and 100μg/L. Total bacterial count was measured after 24 hours. Results showed the sequence of growing rate priority was as...
This study demonstrates the occurrence of 940 organic micro-pollutants in surface water of four rivers, one irrigation canal system, and two lakes in Vojvodina Province, the northern part of Serbia, summing in total eighteen samples. The number of detected chemicals ranged from 22 to 84, with 127 micro-pollutants detected at least once, representing 13% of the studied substances. The targeted compounds...
Adsorption-desorption behaviors of phosphorus (P) on the surface sediments of Yellow River estuary(Y) were investigated in the natural water (river water and seawater) . The results show that(1)The releasing P to the seawater of Y mainly occurs in 0~48h, which occupies 80% of total amount of releasing P. However, releasing P became slowly in 48~96h and according to this speed average kilogram sample...
This paper presents a new headspace-liquid-phase microextraction (HS-LPME) strategy for extraction and preconcentration of benzene, toluene, ethyl- benzene, and o-, m- and p-xylenes (BTEXs) from aqueous samples. A typical room temperature ionic liquid, 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM]PF6), was used as extractant, and the extract was subsequently determined by gas chromatography-hydrogen...
This work addressed the integrated project management of water resources in a costal city, Haihou City in China. Based on investigation of renewable water resources distribution, an underground water storage project was carried out for water safety utility and seawater intrusion prevention in the new planned city area. Methods for surface water reuse and seawater intrusion prevention were integrated...
