AB  - In this study, Mg-based pyro-hydrochars derived from waste grape pomace (Mg-GP), corn cob (Mg-CC), and Miscanthus x giganteus (Mg-MIS) were successfully prepared applying one-step hydrothermal carbonization followed by pyrolysis. The structural characteristics and surface analysis of the prepared materials were characterized by various techniques, while its adsorption ability was examined through remediation of methylene blue (MB) under batch adsorption experiments. The obtained results revealed that pyro-hydrochars are highly effective adsorbents of MB with achieved capacities of 289.65 mg g(-1), 262.30 mg g(-1), and 232.48 mg g(-1) for Mg-GP, Mg-CC and Mg-MIS, respectively. The binding of MB to the surface on either of the tested material was achieved by a complex mechanism that unifies electro-static interaction, hydrogen bonding, pi-pi interaction, surface complexation, and ion-exchange mechanism. The kinetic study display that the adsorption process onto used Mg-doped pyro-hydrochars is favorable and follows pseudo-second order kinetics, while the isotherm equilibriums were determined by Sips isotherm model. Tested materials can be effectively reused for at least 3 cycles, with minimal loss of efficiency. Overall, findings from this work promote Mg-doped pyro-hydrochars form different precursors as promising, sustainable, and efficient adsorbents of MB from polluted wastewaters.

AB  - Primenom zelene tehnologije hidrotermalne karbonizacije (HTC) vlažna tpadna biomasa može se efikasno konvertovati u hidročađ (HC), proizvod sličan uglju, odličnih adsorpcionih karakteristika. HC iako niže poroznosti u odnosu na omercijalne biougljeve, veoma su bogate reaktivnim kiseoničnim funkcionalnim rupama (KFG) koje imaju značajnu ulogu u adsorpciji neorganskih polutanata. Adsorpcija primenom HC miskantusa dobijene HTC-om na 180°S je ispitivana klanjanjem Cu+2, i NH4+ iz vodenih rastvora pri čemu su postignuti maksimalni apaciteti uklanjanja od 310 i 71 mg/g, respektivno. Da bi se dodatno poboljšala posobnost sorpcije teških metala, ispitivane su različite metode aktivacije sovršinske strukture HC. Alkalni tretman HC komine grožđa dobijene HTC-om na 20°S poboljšao je kapacitet uklanjanja Pb+2,Cd+2 i Cu+2 iz vodenog rastvora pet puta, a 137, 49.3 i 38.2 mg/g, respektivno. Kalcifikacijom HC supstrata za gajenje gljiva, obijene HTC-om na 200°S, dizajniran je nov adsorbent Sa-piro-HC za Pb+2 i Cd+2 297 mg/g i 131 mg/g, respektivno).

AB  - Hydrothermal carbonization (HTC) of biomass takes place in a closed reactor at temperatures between 180 - 260° C and self-sustained pressure using the influence of subcritical water as a reaction medium. In most cases, treatment duration is within the range of 1-24 h. The outcomes of the process are, a solid material with a higher carbon content, called hydrochar and the residual HTC wastewater. Due to their surface structure and tunable properties, hydrochars have been applied as been applied as solid fuels, soil conditioners and adsorbents1).
Miscanthus giganteus, a perennial purpose-grown crop, has been primarily used as an energy source. However, with low bulk density and moisture and significant transportation costs, thermochemical pretreatment of this feedstock has been suggested as the best way to overcome these issues and to increase its use-value. Besides, miscanthus is characterized by a very low ash content and this attribute is advantageous for HTC2).
The scope of this work was to offer new insights into the application of miscanthus hydrochars as adsorbent materials. The main objectives were the following: a) valorization of Miscanthus giganteus for the production of an added-value material (adsorbent) at different HTC temperatures and a short residence time b) application of the 'as produced' hydrochars in the adsorption of Cu2+ and NH4+ c) investigation of the influence of the production temperature and correlation of the process severity to the properties and adsorption behaviour of the samples.

AB  - In the framework of bio-circular economy, miscanthus biomass was valorized through a single-stage, low severity hydrothermal carbonization process. The produced hydrochars were characterized using elemental and spectroscopic methodologies. It was determined that as the temperature increased so did the C content (47.9 and 68.9% for the samples prepared at 180 and 260 degrees C, respectively), whereas the O content decreased (from 44.2 to 25.5%, respectively). The adsorption behaviour of the hydrochars was investigated in the adsorption of Cu2+ and NH4+ and MIS-180 was determined as the optimum sample, achieving qmax values of 310 and 71 mg g-1, respectively. Isotherm and kinetic analysis indicated the higher number of O-containing functional groups of MIS-180 as the main reason for its higher adsorption capacities. Furthermore, Cu2+ adsorption followed the 2ndorder kinetic model, whereas NH4+ adsorption followed the 1st-order kinetic model, due to the different mechanisms involved, inner-sphere and outer-sphere complex formation, respectively.

AB  - Based on the concept of circular economy and green chemistry, the conversion of wastes into high added value products should be of great importance. From this point of view, this review chapter summarizes the application of pine-based adsorbents obtained from pine bark, pine cone and pine needles, to adsorb heavy metals, radionuclides, rare earths, and others from aqueous media. Effect of various parameters such as pH, temperature, and contact time is critically presented and discussed in detail. The adsorption capacities, fitted https://www.sciencedirect.com/topics/earth-and-planetary-sciences/isotherm and kinetic models, as well as thermodynamic aspects, are also included in the discussion. The present compilation reveals that generally the experimental data are better fitted by the Langmuir isotherm and pseudo-second-order kinetic models and the adsorption is a spontaneous process. From this literature survey, it is evident that pine-based adsorbents have interesting adsorption properties and could be attractive candidates as adsorbents for inorganic pollutants removal from (waste)water.
