Demineralisation practice will be used to prepare carbons in our lab for 2017 draft plan which permits a highly oxidising atmosphere for this purpose.
treating the raw lignin with sulphuric acid solution (1 wt%) for
1 h, in a proportion of 20 mL of solution per gram of sample, followed
by washing extensively with deionized water until neutral
pH in washing water was attained.
They are average values of triplicate
determinations, where the standard error did not exceed 5%.
Thank you Prof. Mostafa A Hussien. What about thermal treatment and other conditions? Is that enough to get high efficiency demineralisation? What percent we can reach at the end of the experiment (what reference?)? If that low, can we use adsorption? What adsorbents can secure higher removal with good qe value?
