abstract herbicides are the main sources of soil and water pollution in paddy fields. herbicides mobility to the surface and ground water is a major concern for human health and the environment. it is, therefore, necessary to investigate their fate and their interactions in natural ecosystems. to meet this purpose, field experiments were conducted to measure kinetic of thiobencarb dissipation i...

A new and inexpensive lignocellulose/montmorillonite (LNC/MMT) nanocomposite was prepared by a chemical intercalation of LNC into MMT and was subsequently investigated as an adsorbent in batch systems for the adsorption-desorption of Ni(II) ions in an aqueous solution. The optimum conditions for the Ni(II) ion adsorption capacity of the LNC/MMT nanocomposite were studied in detail by varying pa...

Porphyrin-based aluminum metal-organic framework Al-MOF-TCPPH2 compound 1 is synthesized and activated to obtain 2. Its purity demonstrated by ATR-FTIR spectroscopy, spectral assignments of specific functional groups within the TCPP linker are provided as potential binding sites for adsorbate. Compound 2 reversibly sorbs desorbs significant amount water (up 50 wt. %) from humidified air it form...

Solid-state post-combustion CO2 sorbents have certain advantages over traditional aqueous amine systems, including reduced regeneration energy since vaporization of liquid water is avoided, tunable pore morphology, and greater chemical variability. This report includes two parts, i.e., the design and synthesis of nitrogen-doped porous carbons as CO2 sorbents and the development of a robust tech...

phenols are toxic organic compounds and which badly affects the flora and fauna of thebiosphere because phenols are persistent pollutant found in wastewater from many industries. in presentresearch article the photocatalytic removal of o-nitro phenol by synthesized magnetic nanoadsorbents(mna) carried out under photocatalytic reactor. the mna were synthesized by co-precipitation methodrequired ...
