Soil heavy metal pollution caused by human activities has become one of the most critical environmental issues with a global concern. Phytoremediation is widely used due to its low cost and friendliness. However, impact metals on plant growth remains unclear. This study investigated effects photosynthetic activity Picris divaricata Vant. under different cadmium concentrations using hydroponics cultivation system. The results showed that processes P. exhibited phenomenon promotion in Cd...
Colloidal phosphorus (P), defined as P associated with particles within the size range from 1 to 1000 nm, is an often-neglected yet significant component of waterborne P, posing global water quality concerns. This comprehensive review elucidates various sources and concentrations colloidal across diverse environments, highlighting its prominence in agricultural wastewater, mean 122.6 μg/L (n = 437), compared groundwater (52.3 μg/L, n 26), surface freshwater (22.3 246), seawater (5.4 36)....
Abstract Emergent plants have been remarkably effective in reducing phosphorus (P) discharge from ecological ditches; however, the treatment and recycling of these residues is a great challenge. In this study, magnetic biochars (MB s , i.e., MB- A C T ) were fabricated three emergent plant ( Acorus calamus L., Canna indica Thalia dealbata Fraser, respectively) modified with Fe(II)/Fe(III). Scanning electron microscopy-energy dispersive spectroscopy X-ray diffraction spectra confirmed...
Understanding the behavior of colloidal phosphorus (Pcoll) under anoxic conditions is pivotal for addressing soil (P) mobilization and transport its impact on nutrient cycling. Our study investigated Pcoll dynamics in acidic floodplain during a 30-day flooding event. The sudden oxic-to-anoxic shift led to significant rise pore-water levels, which exceeded soluble P levels by more than 2.7-fold. Colloidal fractions transitioned from dispersed forms (<220 nm) colloid-associated microaggregates...
A novel ruthenium(II) complex of [Ru(bpy)2(Hbopip)](ClO4)2 (in which bpy = 2,2'-bipyridine, Hbopip 2-(4-benzoxazolyl)phenylimidazo[4,5-f][1,10]phenanthroline) was synthesized and characterized. The spectrophotometric pH titrations the showed that it acted as a pH-induced luminescence "off−on−off" switch: off−on switch with enhancement factor IpH=3.0/IpH=1.0 20 occurring over narrow range 1.00−3.00 plus on−off 3 3.20−9.40. excited-state ionization constant derived, pKa1* 3.06, is 1.36 pKa...
Glyphosate, which has been widely reported to be a toxic pollutant, is often present at trace amounts in the environment. In this study, novel copper-aluminum metal hydroxide doped graphene nanoprobe (labeled as CuAl–LDH/Gr NC) was first developed construct non-enzymatic electrochemical sensor for detection glyphosate. The characterization results showed that synthesized CuAl–LDH had high-crystallinity flowered structure, abundant metallic bands and an intercalated functional group. After...
Single-entity electrochemistry measurements were used to compare the electrocatalysis of oxygen reduction reaction (ORR) by means multiwalled carbon nanotubes (MWCNTs) or amino-functionalized (MWCNTs-NH2). All evidence showed that an electroactive surface functionality played most important role in catalysis process, not nitrogen content.
Metal–organic frameworks (MOFs) for enzyme encapsulation induced biomimetic mineralization are commonly microporous and hydrophobic, which result in a rather high mass transfer resistance of the reactants restrain catalytic activity.
Phosphate as one of the most essential components living systems, robust analytical techniques available for phosphate sensing in natural waters and soils are monitoring predicting water quality agronomic evaluation phosphate. Using cyclic voltammetry, a point-of-use electrochemical sensor zirconium dioxide/zinc oxide/multiple-wall carbon nanotubes/ammonium molybdate tetrahydrate/screen printed electrode (ZrO2/ZnO/MWCNTs/AMT/SPE) was applied to explore electro-redox reaction phosphomolybdate...
The electrocatalysis of the oxygen reduction reaction (ORR) in aqueous base (0.1 M KOH) by multiwalled carbon nanotubes (MWCNTs) is studied at single entity level. Electroactive surface functionality shown to facilitate significant leading peroxide formation which seen occur lower potentials as compared voltammetric responses obtained bare macroelectrodes and such electrodes modified with layers nanotubes.
We report a novel amperometric sensor for aqueous phosphate ions in freshwater systems based on the reductive square wave voltammetry of molybdate(VI) anions immobilized within chitosan matrix deposited glassy carbon electrode. A sensitivity 4.4 ± 0.1 μA/μM was realized together with LOD 0.15 μM. The insensitive to chloride and nitrate below threshold concentration 1.0 mM. Analytical measurements were successfully made authentic samples tap pond water.
As a critical replenishment source for depleted phosphate in the rhizosphere soil, colloidal phosphorus (Pcoll) of varied sizes has attracted more research interest; however, how to convert Pcoll among subfractions enhance soil P bioavailability remains unclear. In this study, we combined variation microbial community, distribution diffusive gradient thin films (DGT)-labile and acid phosphatase, changes four reveal mechanism synergist derived from plants, improving bioavailability. Results...
Heavy metal pollution in agricultural soil has been tightly associated with anthropogenic emissions. Although there are many studies that focus on a regional scale, the source identification of heavy contamination field scale around industrial areas remains unclear.
