Nitrate Absorption and Desorption by Biochar
نویسندگان
چکیده
Biochar is a potential solution for addressing environmental problems related to excessive nitrogen (N). However, there still some debate about the absorption and desorption of nitrate (NO3−-N). Therefore, this study investigated NO3−-N adsorption performance onto biochar biochar-soil mixture address gap. The results showed that produced from apple branches had ability absorb with an capacity 3.51 mg·g−1. data fitted well pseudo-second-order kinetic model Langmuir model. application significantly improved soil slow release NO3−-N. While higher concentrations better supply poorer slow-release effect. Integrating nutrient effect, it recommended control ratio at 34–42.75 g·g−1. Although unoptimized rate cannot be directly applied as fertilizer carrier meet commercial standards, modification provides new possibilities purpose. Moreover, compared traditional fertilizer, good stability regeneration performance, alleviating high cost due price. In general, has prospects material. This support in mitigating associated excess N.

متن کاملAdsorption and desorption of ammonium by maple wood biochar as a function of oxidation and pH.
The objective of this work was to investigate the retention mechanisms of ammonium in aqueous solution by using progressively oxidized maple wood biochar at different pH values. Hydrogen peroxide was used to oxidize the biochar to pH values ranging from 8.1 to 3.7, with one set being adjusted to a pH of 7 afterwards. Oxidizing the biochars at their lowered pH did not increase their ability to a...
متن کاملAdsorption and desorption of lead in Iranian acid and alkaline soils amended with sewage sludge-derived biochar
The effective management of sewage sludge materials in an environmentally and economically acceptable way is through the pyrolytic conversion of the sludge to biochar and its use for agricultural purposes. The aims of this work were: (1) to assess the effect of biochar prepared from sewage sludge at two different temperatures (350 ºC and 650 ºC) on the adsorption/desorptio...
متن کاملMoisture absorption-desorption effects in adhesive joints
This paper presents a study of moisture absorption-desorption effects in single lap adhesive joints. Experiments were carried out to characterise the moisture uptake of the single part epoxide adhesive, FM73. Tensile testing of single lap joints manufactured from aluminium alloy 2024 T3 and O and FM73 adhesive was carried out after the joints were exposed to different conditioning environments....
