Ash-biochar composites with high alkalinity increase soil pH, favouring the electrostatic interactions for metallic cations and negatively charged soil colloids (Lei et al., 2020). Nano zero valent iron– and iron sulphide–biochar composites promote soil Cr(VI) reduction (Liu, Yang, et al., 2020; Lyu, Zhao, et al., 2018; Wang et al., 2019).

In a typical procedure, solid biochar and balls were weighed according to statistical plan, placed in a jar and ground until the desired time. A 5-min rest interval was considered after each 5-min grinding to prevent temperature build-up. Sampling was performed at the end of grinding. 2.3. Ball milling of biochar and optimization
Biochar was synthesized from biomass (jatropha seeds) through a low microwave pyrolysis temperature of 180 °C with microwave power of 2kW. A ball milling process reduced the jatropha seed biochar size and converted it into micro-nano carbon

Biochar-based fertilizers are a new attractive alternative to P supplementation for crops, as they can gradually release the nutrient, avoiding losses and improving soil quality. In this regard, the evaluation of the P amount in biochar-based fertilizers is extremely important for their quality control. Analytical techniques that require sample solubilization are not very efficient for …

The modified biochar prepared by H 2 SO 4 produced a large amount of C═O (C3). The production of C3 was due to the high oxidation state of C in the C═O and HO–C–OH structures, which produced a large amount of ketones. Analysis showed that the strong oxidation of sulfuric acid led to an increase in double bonds.

procedures described here, the reader should refer to recent bulletins compiled by the various regional committees working on nutrient analysis of soils, plants, water, and waste materials (SERA-IEG-6, NCERA-13 and NEC-67). More detailed information on analysis of animal manures can be found in the publication "Recommended Methods for
Titanium and its alloys have superb biocompatibility, low elastic modulus, and favorable corrosion resistance. These exceptional properties lead to its wide use as a medical implant material. Titanium itself does not have antibacterial properties, so bacteria can gather and adhere to its surface resulting in infection issues. The infection is among the main reasons for …
Analysis of biochar. The biochar yield produced from Cannabis and Parthenium after catalytic gasification is 34.66% and 38.36%, respectively, which shows that biochar yield from Parthenium hysterophorus L. is higher as compare to Cannabis sativa L. The detailed analysis of the derived biochar is summarized in Table 5.
