“…Soda pulping has been well studied by the Forestry and Forest Products Research Institute, Tsukuba, Japan as a delignification process for bioethanol production based on cedar wood via enzymatic saccharification. Therefore, SL may be regarded as a commercially available technical lignin (Gosselink et al 2004). However, cedar SL is not fusible; thus, SL was converted to fibers by dry electrospinning.…”

Electrodes has been prepared for application in an electric double layer capacitor (EDLC) based on polyethylene glycol lignin (PEGL) and soda lignin (SL) derived from cedar wood. Fibers with a diameter of 23 μm were prepared by direct melt electrospinning of PEGL. Much finer fibers of 3.6 μm diameter were obtained by dry electrospinning of 70% PEGL in a dimethyl formamide (DMF) solution at 145°C. The dry electrospinning of SL alone in an alkaline aqueous solution was not achievable, but this was possible of a mixture of SL and polyethylene glycol (M w = 500 000) at a ratio of 99/1, which resulted in thin SL fibers with a diameter of 0.85 μm. These fibers were converted into activated carbon fibers (ACFs) by thermostabilization, carbonization, and steam activation. The specific Brunauer, Emmett and Teller (BET) surface areas of the resulting PEGL-ACFs and SL-ACFs were 1880 m 2 g -1 and 1411 m 2 g -1 , respectively. PEGL-ACFs electrodes with an organic electrolyte exhibited an impedance of 1.6 Ω and a specific capacitance of 92.6 F g -1 at a scan rate of 1 A g -1 , and the SL-ACFs electrodes had an impedance and specific capacitance of 4.5 Ω and 55.6 F g -1 , respectively.

This study investigated the adsorption of the heavy metal ions Pb(II), Cu(II), Cd(II), Zn(II), and Ni(II) on a lignin isolated from black liquor, a waste product of the paper industry. Lignin has affinity with metal ions in the following order: Pb(II) > Cu(II) > Cd(II) > Zn(II) > Ni(II). The adsorption kinetic data can be described well with a pseudosecond-order model and the equilibrium data can be fitted well to the Langmuir isotherm. Metal ion adsorption was strongly dependent on pH and ionic strength. Surface complexation modelling was performed to elucidate the adsorption mechanism involved. This shows that lignin surfaces contain two main types of acid sites attributed to carboxylic-and phenolic-type surface groups and the phenolic sites have a higher affinity for metal ions than the carboxylic sites.

“…These technical lignins are a yet sparsely used mass-product. About 10% of the technical lignins are exploited industrially whilst the rest is combusted or not utilised at all (Kharazipour et al 1991, Northey 1992, Gargulak & Lebo 2000, Lora & Glasser 2002, Chakar & Ragauskas 2004, Gosselink et al 2004a. With the invention of the "Pedersen-process" in the late 1960s, technical lignins have found for the first time on semi-industrial scale usage as binders in wood composite production (Pedersen & Rasmussen 1966, Roffael & Dix 1991.…”
