Laser-induced breakdown spectroscopy determination of K in biochar-based fertilizers in the presence of easily ionizable element
(2018-10-01)
Laser-induced breakdown spectroscopy is an optical emission technique quite suitable for the analysis of recalcitrant materials as it eliminates complex procedures of sample preparation. However, for some simple LIBS ...
Total carbon measurement in whole tropical soil sample
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Soils are an important component in the biogeochemical cycle of carbon, storing about four times more carbon than biomass plants and nearly three times more than the atmosphere. Moreover, the carbon content is directly ...
Assessment of sorption capability of montmorillonite clay for lead removal from water using laser–induced breakdown spectroscopy and atomic absorption spectroscopy
(Elsevier Science, 2019-01)
Laser-induced breakdown spectroscopy (LIBS) and atomic absorption spectroscopy (AAS) techniques were applied for quantitative analysis of the remaining Pb content in water samples after treatment with a raw montmorillonite ...

Calcium determination in biochar-based fertilizers by laser-induced breakdown spectroscopy using sodium as internal standard
(2017-09-01)
Biochar has gained agricultural importance as a soil amendment because of its important agricultural properties such as water retention, plant nutrient supplier, promoter of microorganism growth, sequestration action of ...
Uso de métodos baseados em laser para caracterização da matéria orgânica em solos
(Universidade Federal de São CarlosUFSCarCâmpus São CarlosQuímica - Q, 2022-08-26)
The growing interest in biogeological carbon sequestration to avoid or offset CO2 emissions, mainly in the interest of generating carbon credits, has stimulated the need to develop monitoring approaches by companies and ...
