“…Surface amination is one of the most widely used methods to introduce amino groups into biochar. Ammonia (NH3) treatment at high temperatures is a conventional surface amination technique that has been used extensively for decades [39]. Alternatively, chemical modification using some amino containing reagents is an environmentally friendly method also used for the surface amination of biochar.…”

Biomass can be converted to biofuels and bioproducts via thermochemical processes. Biochar is one of the major products of thermochemical conversion of biomass. The efficient use of biochar is critical to improving the economic viability and environmental sustainability of biomass conversion technologies. Applications of biochar for both agricultural and environmental benefits (e.g. as soil amendment, for inorganic pollutant removal) have been studied and reviewed extensively. However, biochar for energy storage materials and catalytic applications has not been widely reviewed in the recent past. This review aims to present the more significant recent advances in several biochar utilizations such as catalysts and supercapacitors. Discussions on biochar production technologies, chemistry, properties, characteristics, and advanced functionalization techniques are provided. It also points out barriers to achieving improvements in the future.

“…4) was used to predict the studied variable factors as a function of independent variables and the interaction among them: (4) where, Y is the predicted dependent variable, b 0 is constant coefficient, b i , b ii and b ij are regression coefficients, i and j are index numbers, k is number of patterns, X i and X j are independent variables and ε is the random error. 24 The analysis of variance (ANOVA) was used to assess the significance and adequacy of the model. The fitness of the polynomial models was expressed by the coefficients of determination, R 2 , R 2 adj and R 2 pred .…”

Oxidative treatment of a cationic dye solution, methylene blue, was investigated using magnetite nanoparticles and goethite in heterogeneous Fenton-like reaction, and ferrous ions in homogeneous Fenton-reaction. The aim was to compare the degradation efficiencies of the studied catalysts for decolorization of methylene blue solution as the model organic pollutant. Response surface methodology (RSM) was applied to determine the optimal operational conditions for magnetite/H 2 O 2 and goethite/H 2 O 2 systems. The [H 2 O 2 ] of 0.2 M, catalyst dosage of 1 g/L, pH 9.0 and reaction time of 5h were chosen by RSM. The pH value of 3.0 was used in the case of Fe +2 /H 2 O 2 system. The experimental results showed that homogeneous Fenton oxidation system was the most effective system under both acidic and neutral conditions but decreased at pH value of 9.0 due to the decrease in available Fe 2+ ions in the solution and generation of ferric hydroxide sludge. Fe 3 O 4 /H 2 O 2 system represented better removal efficiency than FeO(OH)/H 2 O 2 system that could be attributed to the presence of Fe II cations in magnetite structure and its larger surface area.

Considering the rich sugar beet resource in Xinjiang, China, the possibilities for Hg(II) removal by pectin extracted from sugar beet pulp and optimization of the extraction process using response surface methodology (RSM) were studied. The experiments were proposed by Box-Behnken design (BBD) and a second-order regression model was developed for regression analysis and analysis of variance. Optimized conditions in terms of temperature, concentration, and solid-liquid ratio were determined. The effects of different parameters like pH, time, temperature, and initial Hg(II) concentration on adsorption capacity were investigated. The isotherm adsorption experiments were fitted with the Langmuir model which indicated monolayer adsorption.
