The property of groundwater dissolved organic matter (DOM) subjected to anthropogenic recharge (AGR) might be affected by the water quality disparity between surface and natural groundwater. However, diverse molecular scenarios DOM under uneven recharging levels remain largely unexplored. We combined characteristics, carbon isotopic signatures molecules, end-member mixing analysis explore sensitivity potential tracking capabilities AGR along with gradients. Our findings suggested that...
This study explored the stratigraphic distribution and soil/shallow aquifer characteristics surrounding a chromium ore processing residue (COPR) dumpsite at former chemical factory in China. Total Cr levels top soils (5–10 cm) nearby COPR were range of 8571.4–10711.4 mg/kg. Shallow aquifers (1–6 m) showed maximum total level 9756.7 The concentrations Cr(VI) groundwater 766.9–1347.5 mg/L. These results display that soils, shallow aquifers, site are severely polluted by Cr(VI). Then, three...
Traditional underwater target object detection technologies such as sonar and optical imaging can't be well applied to harsh environment. Inspired by the biological perception of weak electric fish, an moving localisation method based on active field sensing principle Long Short Term Memory (LSTM) network is proposed in this paper. A sensor array with 4 Held emitting electrodes 16 receiving designed, LSTM 6- layer architecture constructed. The pool experiment results show that predicted...
The kinetic, equiLibrium and thermodynamics of Cr(VI) adsorption from aqueous solution on cetylpyridinium bromide (CPB) modified zeoLite were investigated. CPB displayed a good affinity to in solution, its capacity decreased with the increase temperature. kinetics discussed using pseudo-first-order pseudo-second-order kinetic models, experimental data agreed very well model. isotherms analyzed by Langmuir, FreundLich Dubinin-Redushkevich (D-R) isotherm described all these models....
Surfactant-modified zeolites (SMZ) with different coverage types were prepared by loading the cetylpyridinium bromide (CPB) onto surface of natural zeolite collected from Jinyun County, Zhejiang Province, China. The adsorption behavior Cr(VI) on SMZ was investigated. Natural and CPB monolayer inefficient for removal aqueous solution. However, patchy bilayer or efficient in capacity increased its loading. showed a maximum at pH 3-6 decreased increasing 6 to 11. presence competing anions such...
Novel monodispersed pompon-like magnetite/chitosan (Fe3O4/CS) composite nanoparticles were synthesized by a solvothermal method and used as adsorbents for the removal of toxic sodium pentachlorophenate (PCP-Na) from aqueous media. The adsorption behavior PCP-Na on Fe3O4/CS obeyed Langmuir isotherm fitted pseudo-second-order kinetics model. Thermodynamic parameters showed that process was exothermic spontaneous. Moreover, strongly pH-dependent. results XPS, thermodynamics, pH-dependent...
The inverted pendulum system is a typical nonlinear, multivariable, and strong coupling system.In this paper, the structure of introduced in detail.The produced by Quanser Company Canada taken as research object.Based on LabVIEW software, can be swing up automatically energy method.The result suggests that regulator designed article shows great control.
Due to the combined effect of sluices and sea tide, sluice-controlled coastal plain river would be characterized by both trophic state salinity gradients, affecting spatiotemporal optical properties dissolved organic matter (DOM). In this study, we investigated variation water quality parameters DOM in Haihe River, a representative Tianjin, China. A significant gradient four states were observed body River. The upstream downstream Erdao Sluice with values 0.02-0.39 2.07-7.85 displayed as an...
