“…It is also known that dehydration of boric acid under heat yields some forms of boric oxide depending on temperature level, and on the other hand, boric acid itself can be vaporised under heat. Similarly, as written by Kataoka et al (2008), it is well known that boric acid and its salts sodium tetraborate and sodium metaborate are all volatile. Especially in acidic media (such as liquefied wood in our experiment) the volatilities are extremely increased.…”

There are high amounts of post-consumed protected waste wood removed from service every year. The residual biocides, including copper, chromium and boron from CCB (Cu, Cr, B) in post-consumed wood that was protected with biocides may cause environmental problems during waste management, for example during land filling. Therefore, the aim of this study was to find out if Cu and Cr in the processed waste wood, previously treated with CCB, can be re-used as a wood preservative or in coatings made of liquefied wood. Liquefaction of CCB containing waste wood could be as well the first step in the elimination process of metals. So, the optimal conditions for liquefaction of CCB (Cu, Cr and B) containing black poplar (Populus nigra L.) wood were established and compared with liquefaction of uncontaminated black poplar wood. The reactants for liquefaction of black poplar wood sawdust were ethylene glycol (EG) and sulphuric acid. It was observed that in the last stages of the liquefaction process, the presence of Cu, Cr and B did not have any influence on liquefaction yield (LY), while their influence was observed in first stages of the solvolytic reaction. Investigations of fungicidal properties of uncontaminated and CCB containing liquefied wood showed higher antifungal efficacy of liquefied wood without Cu, Cr and B than of liquefied wood that contained CCB. In the tested concentration range, the presence of Cu even promoted the growth of selected wood decay fungi. One of the reasons for higher toxicity of liquefied black poplar sawdust without Cu, Cr and B, was its very low pH value.

“…Okamoto et al demonstrated the possibilities of both ETV-ICP-OES and ETV-ICP-MS for speciation of different boron species in biological and steel samples, after sample dissolution. 167,168 ETV-ICP-OES and ETV-ICP-MS have been widely used for speciation studies in combination with separation/preconcentration techniques. 14 Hu and coworkers used ETV-ICP-OES for speciation of V(IV) and V(V), [169][170][171] Fe(II) and Fe(III), 172,173 Cr(III) and Cr(VI), 174,175 and Sb(III) and Sb(V), 176 whereas ETV-ICP-MS was used for speciation of Se(IV) and Se(VI).…”

“…The tungsten boat furnace (TBF) ICP-MS and TBF-ICP-AES was investigated to determine the volatile boric acid and total boron according to different vaporisation properties of boron compounds. 7) Due to the detection limit level and complex sample preparation procedures, these methods present certain restrictions for the real-time monitoring of iron and steel manufacturing processes. Laser-induced breakdown spectroscopy (LIBS) as an analytical detection technique based on atomic emission spectroscopy has attracted a great attention in various industries because of the non-contact, fast response and multi-dimensional features as the qualitative and quantitative analytical detection technique.…”

The metallurgical industries are very important for social development. In order to improve the metallurgical techniques and quality of products, the real-time analysis and monitoring of iron and steel manufacturing processes are very significant. Laser-induced breakdown spectroscopy (LIBS) has been studied and applied for the contents measurement of iron and steel. In this paper, the remote open-path LIBS measurement was studied under different sample temperature, lens to target distance (LTD), sample angle conditions to clarify its online measurement features. The 3D profile measurement system of parallel laser beam fringes projection was also developed to measure the sample profile at different sample temperature. The measurement results demonstrated the robustness of remote open-path LIBS system and 3D profile measurement system. However, the correction is necessary to enhance the detection ability of LIBS online measurement. In order to improve the precision and accuracy of real-time elemental measurement, an innovative co-axial laser beam measurement system combining LIBS and 3D profile techniques is proposed to automatically adjust the focus unit and measure the sample components. The further study of this promising method will be developed for online application of iron and steel manufacturing processes. KEY WORDS: laser-induced breakdown spectroscopy; 3D profile; remote measurement; iron and steel manufacturing processes.
