Adriana Pires Vieira,Sirlane A.A. Santana,Cícero Wellington Brito Bezerra,Hildo Antonio dos Santos Silva,José Alberto Pestana Chaves,Júlio C.P. de Melo,Edson Cavalcanti da Silva Filho,Claudio Airoldi +7 more
TL;DR: The results pointed to the effectiveness of the mesocarp of babassu coconut as a biosorbent for removing textile dyes from aqueous solutions.
Journal ArticleDOI
Composition and rheological properties of Albizia lebbeck gum exudate
TL;DR: In this article, the composition, structure and rheological properties of Albizia lebbeck gum from Brazilian plants were investigated and the main chain is composed of galactan core (1→3) linked with approximately 33% of substitution at C-6.
Journal ArticleDOI
Maleic anhydride incorporated onto cellulose and thermodynamics of cation-exchange process at the solid/liquid interface
TL;DR: In this article, a quasi-solvent-free procedure was used to add a biopolymer to molten maleic anhydride, producing a mixture of maleated and fumarated celluloses.
Journal ArticleDOI
Copper sorption from aqueous solutions and sugar cane spirits by chemically modified babassu coconut (Orbignya speciosa) mesocarp
Adriana Pires Vieira,Sirlane A.A. Santana,Cícero Wellington Brito Bezerra,Hildo Antonio dos Santos Silva,Júlio C.P. de Melo,Edson Cavalcanti da Silva Filho,Claudio Airoldi +6 more
TL;DR: In this paper, the chemical modification of natural dry babassu coconut ( Orbignya speciosa ) mesocarp (BM), using a quasi solvent-free procedure in which the precursor was added to molten succinic (S), maleic (M) or phthalic (P) anhydrides, to give new products named BMS, BMM and BMP.
Journal ArticleDOI
Removal of textile dyes from aqueous solution by babassu coconut epicarp (Orbignya speciosa)
Adriana Pires Vieira,Sirlane A.A. Santana,Cícero Wellington Brito Bezerra,Hildo Antonio dos Santos Silva,José Alberto Pestana Chaves,Júlio C.P. de Melo,Edson Cavalcanti da Silva Filho,Claudio Airoldi +7 more
TL;DR: In this paper, Babassu coconut epicarp was used as biomass to remove textile dyes from aqueous solution, and the effects of contact time and concentration on the sorption of the textile dye onto the epicarp were investigated.
