“…It was observed that the percentage degradation of 2,6-DCP in soil increased with the increase in the PPAC dosage. A similar observation has been reported for the use of bamboo biochar on pentachlorophenol leachability and bioavailability in agricultural soil [53]. …”

“…Enhanced bioremediation of soil highly contaminated with herbicide propanil (3',4'-dichloropropionanilide) in the Krasnodar region of Russia, 3,4-dichloroaniline, polychlorinated biphenyls (PCB) and 2,4,6-trinitrotoluene (TNT) in the presence of activated carbon have been reported [48][49][50][51][52]. Accelerated biodegradation of anthracene in the presence of groundnut shellderived activated carbon has been reported by Owabor and Aluyor [28] while Lou et al [53] have also observed accelerated biodegradation of pentachlorophenol in soil in the presence of bamboo biochar. However, the percentage degradation of 2,6-DCP in PPAC-amended soil is relatively greater than the NPK fertilizer-amended soil.…”

In this study, the potential effects of palm kernel oil (PKO), pineapple peels derived-activated carbon (PPAC) and NPK fertilizer (20:10:10) as amendment agents on the natural bioattenuation of 2,6-dichlorophenol (2,6-DCP) in tropical agricultural soil were investigated. The effect of PPAC dosage on 2,6-DCP biodegradation was also studied. Column reactors containing soil were spiked with 2,6-dichlorophenol (2,6-DCP) wastewater (300 mg/l) and amended with PKO, NPK fertilizer and PPAC alone or in combinations. The rates of 2,6-DCP biodegradation were studied for a remediation period of 42 days under laboratory conditions. The results showed that there was a positive relationship between the rate of 2,6-DCP biodegradation, bacterial growth rate and presence of NPK fertilizer and PPAC (alone or in combination) in soil column microcosms contaminated with 2,6-DCP. The 2,6-DCP biodegradation data fitted well to the first-order kinetic model. The model revealed that 2,6-DCP contaminated-soil microcosms amended with NPK fertilizer and PPAC (alone or in combination) had higher biodegradation rate constants (k) as well as lower half-life times (t 1/2 ) than soil column microcosms amended with PKO and unamended soil (natural attenuation) remediation system. Thus, the use of combined NPK fertilizer and activated carbon (NPK + PPAC) to enhance 2,6-DCP degradation in the soil could be one of the severally sought bioremediation strategies of remediating natural ecosystem (environment) contaminated with organic chemicals.

Improving the soil and biomass with coal is estimated at the international level as a way to enhance soil productiveness, fertility and also to mitigate climate change. Biochar employed to improve land scope and impound carbon, is attracting a great deal of attention. Its characteristics of chemical, physical and biological properties, containing big surface area, CEC (Cation Exchange Capacity), high water-holding capacity, size of pore, volume, distribution, and element composition, affect its recognized influences, particularly on microbial communities. These are discovered in the agriculture lands, lands remediation and composting. However, incomplete information existed about biochar for several farmers or peasants in agriculture scope. Therefore, farmers or peasants and gardeners are facing new opportunities and defiance each day, from feeding global extending and expanding population, whilst meeting severe new emissions requirements, to create more food on fewer land area while reducing their environmental emissions. Widespread application and utilization of biochar in agricultural scope, forestry production, energy, environmental protection and additional areas, has interested awareness by scientists and investigators inside and/or outside the country. The objective of this paper is to provide a guide for the farmers or peasants and gardeners with an essential information about biochar and what the ability of biochar can be achieved in the soil, and which can provide the scientific reference for the biochar application, and to get high yield and good quality of crops in all of different soils.

“…Activated carbon adsorption has been recognized as the most effective method, producing good-quality effluents that have low concentrations of dissolved organic compounds in wastewater from pharmaceutical manufacturing [4]. Due to the high operational cost of the traditional activated carbon adsorption techniques, many low cost adsorbents have been used to remove various pollutants [5][6][7][8]. Among these adsorbents, bamboo biochar has shown promising application for the removal of organic pollutants [5].…”

Abstract:The occurrence of fluoroquinolone antibiotics in wastewater has drawn great attention. Adsorption of widely used fluoroquinolone antibiotics (enrofloxacin and ofloxacin) in wastewater using bamboo biochar was investigated. More than 99% of fluoroquinolone antibiotics were removed from the synthetic wastewater through adsorption. Adsorption capacities of bamboo biochar slightly changed when pH increased from 3.0 to 10.0. The adsorption capacity of bamboo biochar increased sharply when the initial concentration of enrofloxacin or ofloxacin increased from 1 to 200 mg L
