“…Uchimiya et al (2011c) also found similar results for Cu retention in two soils (Norfolk and San Joaquin), with distinct characteristics. In Norfolk soil, biochar enhanced Cu retention mainly by the cation exchange mechanism, while for San Joaquin soil, additional mechanisms such as electrostatic interactions, sorption, complexation, and precipitation were responsible for controlling Cu adsorption.…”

“…Also, the biochar surrounds a non-carbonized fraction that may undergo change with soil impurities. Specially, the level of oxygen containing carboxyl, hydroxyl, and phenolic surface functional groups in biochar could efficiently hold together the soil contaminants (Uchimiya et al 2011a). The interaction of different metals with biochars is a complex function of pH such as (1) the biochar functions vary with pH and (2) the metals pollutant ion speciation changes with pH that leads to a far more complex situation than either alone.…”

Biochar simply is the material produced when biomass undergoes any chemical processes under the conditions of pyrolysis. The variety of biomasses, including wood waste, agricultural crop leftover, organic waste, animal manure, and forestry residues, have been considered as raw material to produce biochar. Biochar is widely used for generation of heat and power and an addition to soils, in which it serves as a fertilizer and carbon sequestration agent. Also in the form of being activated, it finds significant role for various adsorption applications. The most beneficial use of a given char depends on its physical and chemical characteristics, even though the relationship of char properties to these applications is not well defined. Various widely used modern analytical techniques, which are applicable and crucial for biochar characterization, have been reviewed in the present work, such as solid state nuclear magnetic resonance spectroscopy, Fourier transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, X-rays photoelectron spectroscopy, X-rays diffraction, thermogravimetric analysis, near edge X-rays absorption fine structure spectroscopy, and gas chromatography-mass spectroscopy. Utilization of these modern techniques provides the quantitative as well as qualitative information, i.e., determining the sizes, shapes, and physicochemical characteristics of biochar, which is reliable to track changes in the carbon arrangement over reaction time and temperature, and will be useful for efficient production of biochar and application. It provides the useful information for the researchers in this area and is beneficial not only for the effective biochar production, but also for potential utilization/application, and not only for environment but also for agriculture.

“…The FTIR spectrum of ZnO NPs was recorded from 200 to 3000 cm -1 . As shown in Figure. 2, the following bands were observed: a band at 2924 cm -1 corresponding to stretching vibration of CH3; bands at 2924 and 2854 cm -1 corresponding to antisymmetric and symmetric stretching of C-H [17]; a band at 1505 cm -1 corresponding to -C H2 deformation and Zn-O stretching; and a band at 1044 cm -1 corresponding to C-O stretching peak [18], and a band at 834 cm -1 corresponding to C-H bending aromatic CH out-of-plane deformation. Parthasarathi and Thilagavathi [19] reported similar FTIR spectra observed of zinc oxide nanoparticles in their investigation.…”

Nanoparticles of zinc oxide (ZnO NPs) using the precursor citrate was formed as a single phase one stage with the size of 25 nm. ZnO NPs was used at different concentrations (1, 2, 5 mML -1 ) in some edible oils [cotton seed oil and its blend with palm Olean in the ratio of 1:1 (v/v) during heat stress as antioxidant. Some of the chemical characteristics of the oil were estimated as an indicator of deterioration as a result of oxidation during thermal stress within two hours. The results revealed that chemical characteristics (e.g. PV, p-AV and Totox value) of oils that contained 1mML -1 ZnO NPs were not affected significantly compared to those free from ZnO NPs during heat stress. These results suggested that ZnO NPs has a potential power to control the oxidation process during heat stress of edible oil and could be used as synthetic antioxidant agent. More studies concerning the solubility of ZnO NPs and its nutritional effect on the animal lab are needed.
