Adsorptive Removal of Acid Fuchsin Dye Using By-Product Silica Fume and Laccase-Modified Silica Fume

Silica fume, also referred to as micro silica, is a spin-off of the decrease of high-purity quartz with coal in electrical heating systems in the manufacturing of silicon and ferrosilicon alloys. This material and laccase-modified silica fume utilized as alternative inexpensive adsorbent materials for dye removal from liquid solutions. These specifications showed that the adsorption of Acid Fuchsin color onto silica fume and laccase-modified silica fume was a spontaneous, endothermic, and entropy-driven procedure. The results show that both of them, particularly laccase-modified silica fume, can be made use of as alternative affordable adsorbents for color elimination from aqueous tinted options or effluents.

Scientific Opinion on the safety evaluation of a time-temperature indicator system, based on Carnobacterium maltaromaticum and acid fuchsin for use in food contact materials

The Panel noted that the layer of the plastic sachet in contact with food contact write-ups behaves as a barrier which prevents any release of its content, and that the sachet is stuck onto the outer layer of the product packaging, hence is not in contact with the food. The Panel concluded that the substances of the smart system, C. maltaromaticum and acid fuchsin, do not elevate a safety worry for the customer when utilized in a plastic sachet which avoids any migration from the system into food and which is stuck onto the outer layer of the product packaging of cooled food.

Co-immobilization of laccase and TEMPO onto amino-functionalized magnetic Fe3O4 nanoparticles and its application in acid fuchsin decolorization

Cause this research, amino-functionalized magnetic Fe3O4 nanoparticles were synthesized for co-immobilization of 2,2,6,6-tetramethylpiperidine-1-oxyl and laccase by glutaraldehyde cross-linking approach. Cyclic voltammetry was carried out to confirm electrochemical habits of the co-immobilized laccase and TEMPO nanoparticles. When the co-immobilized laccase and TEMPO nanoparticles were utilized to decolorize acid fuchsin, the maximum decolorization rate of 77. 41% was acquired with the proportion of TEMPO to laccase being 0. 3 mM/g:120 U/g. Final thought The co-immobilized nanoparticles retained over 50% residual activity after eight cycles of procedure, which provided a strategy to develop a co-immobilized laccase and arbitrator system for potential industrial application.
