“…Therefore, NO 3 – might be adsorbed by base functional groups in bagasse charcoals. Banno et al (2009) reached the same conclusion for bamboo charcoal. Because bagasse charcoals formed at pyrolysis temperatures higher than 700°C were effective in NO 3 – adsorption, we used a bagasse charcoal formed at 800°C for the subsequent experiments.…”

“…Biochar, charcoal produced from pyrolysis of biomass, has a fine porous structure and a potential use as an adsorbent. Biochar can adsorb dissolved NO 3 − (Banno et al, 2009; Mishra and Patel, 2009; Mizuta et al, 2004; Mori et al, 2001; Ohe et al, 2003). If biochar application to farmlands increases NO 3 − adsorption, then residence time of NO 3 − in the root zone of crops will increase and biochar‐amended soils will provide greater opportunity for crops to absorb NO 3 − .…”

Influence of Sugarcane Bagasse-derived Biochar Application on Nitrate Leaching in Calcaric Dark Red Soil

et al. 2012

Application of biochar has been suggested to improve water‐ and fertilizer‐retaining capacity of agricultural soil. The objective of this study was to evaluate the effects of bagasse charcoal (sugarcane [Saccharum officinarum L.] bagasse–derived biochar) on nitrate (NO3−) leaching from Shimajiri Maji soil, which has low water‐ and fertilizer‐retaining capacity. The nitrate adsorption properties of bagasse charcoal formed at five pyrolysis temperatures (400–800°C) were investigated to select the most suitable bagasse charcoal for NO3− adsorption. Nitrate was able to adsorb onto the bagasse charcoal formed at pyrolysis temperatures of 700 to 800°C. Nitrate adsorption by bagasse charcoal (formed at 800°C) that passed through a 2‐mm sieve was in a state of nonequilibrium even at 20 h after the addition of 20 mg N L−1 KNO3 solution. Measurements suggested that the saturated and unsaturated hydraulic conductivity of bagasse charcoal (800°C)–amended soils are affected by changes in soil tortuosity and porosity and the presence of meso‐ and micropores in the bagasse charcoal, which did not contribute to soil water transfer. In NO3− leaching studies using bagasse charcoal (800°C)–amended soils with different charcoal contents (0–10% [w/w]), the maximum concentration of NO3− in effluents from bagasse charcoal–amended soil columns was approximately 5% less than that from a nonamended soil column because of NO3− adsorption by bagasse charcoal (800°C). We conclude that application of bagasse charcoal (800°C) to the soil will increase the residence time of NO3− in the root zone of crops and provide greater opportunity for crops to absorb NO3−.

“…The chemical properties, including the NO 3 -N adsorption property, of BC depend on the biomass feedstock and on the pyrolysis conditions, particularly on pyrolysis temperature (Chia et al 2015). Banno et al (2009) demonstrated that the NO 3 -N adsorption of the BC formed at 800°C was significantly higher than that formed below 600°C for moso bamboo. In addition, Kameyama et al (2012) demonstrated that the NO 3 -N adsorption of the BC formed above 700°C was significantly higher than that below 600°C for sugarcane bagasse.…”

“…In addition, Banno et al (2009) and Kameyama et al (2012) suggested that the NO 3 -N adsorption of BC may be mainly due to base functional groups and not due to physical sorption. Therefore, NO 3 -N adsorption by BC may be related to the amount of surface basic functional groups.…”

Biochar (BC), charcoal produced through the pyrolysis of biomass, is reported to adsorb dissolved nitrate-nitrogen (NO 3-N). The NO 3-N adsorption properties of BC differ depending on the feedstock and the pyrolysis conditions, and the influences have not been systematically clarified. Therefore, we evaluated the dependence of feedstock and pyrolysis temperature on the NO 3-N adsorption properties of BC. Wood chips [Japanese cedar [Cryptomeria japonica] (CE) and Japanese cypress [Chamaecyparis obtusa] (CY)], moso bamboo [Phyllostachys edulis] chips (MB), rice [Oryza sativa] husks (RH), sugarcane [Saccharum officinarum] bagasse (SB), poultry manure (PM) and domestic wastewater sludge (WS) were air-dried and heated in a batch-type carbonization furnace at pyrolysis temperatures of 400, 600 and 800°C, with a hold time of 2 h. Among the BC produced from each feedstock, the one produced at 800°C had the greatest NO 3-N adsorption. The NO 3-N adsorption by BC produced from wood-based biomass at 800°C was significantly higher than that of the BC produced from non-wood-based biomass at 800°C. Therefore, BC made from wood-based biomass at higher temperature can be adequate as soil amendment material for adsorption of NO 3-N.

“…OC carbonised at 400°C and 600°C and it shows a decrease in pH due to air oxidation. The pH of bamboo charcoal is related to the alkaline mineral content and acidic functional groups [1,3]. The reason for the pH of AC (400°C and 600°C) tending to be more acidic than OC may be attributed to the increase in the acidic functionality.…”

We developed an activated charcoal by creating bamboo charcoal that was carbonised at a temperature between 400 to 1000°C and then kept it at a temperature of 270°C for 2 h. One gram of activated charcoal was added to 100 mL of aqueous caesium of 2.67 × 10-2 mmol/L and 100 mL of strontium aqueous solution, and was stirred for 1 h. The caesium adsorption amount of bamboo charcoal, which was carbonised at 400°C, increased from 70.0% to 88.9%. In addition, the amount of strontium absorbed increased from 76.5%
