We also wish to extend our grateful appreciation to Rosario Portales, Todd Kelly and Richard Buran for their contributions and critical comments regarding this research.The ability of biological and non-biological adsorbents to remove 2-nitrophenol (2-NP) and 2-chlorophenol (2-CP) from aqueous solutions in batch experiments at room temperature was compared. The marine seaweeds Macrocystis integrifolia Bory (S1) and Lessonia nigrescens Bory (S2) were cross-linked with CaCl2 to enhance their mechanical properties. Natural bentonite was chemically exchanged with hexadecyltrimethylammonium bromide (B1) and bencyltriethylammonium chloride (B2) to increase their affinity towards organic compounds as well. The adsorption capacity of all of the adsorbents strongly depends on solution pH, whereas equilibrium assays showed a mixed mechanism according to the Langmuir and Freundlich isotherms. The maximum adsorption capacity of 2-NP follows the trend: S1 > S2 > B2 > B1 within the range of 97.37 and 18.64 mg g−1 whereas for 2-CP, it ranged between 24.18 and 9.95 mg g−1 with the trend: S1 > S2 > B2 ≈ B1. The importance of the octanol–water partition coefficient as the main factor on the adsorption of these compounds on two different kinds of adsorbents is discussed.Consejo Nacional de Ciencia, Tecnología e Innovación Tecnológica - ConcytecengElsevierinfo:eu-repo/semantics/openAccesspHExchanged bentonite-1Cross-linked algae-1Partition coefficient-1Adsorption-1https://purl.org/pe-repo/ocde/ford#1.06.03-1Comparative study of the removal of phenolic compounds by biological and non-biological adsorbentsinfo:eu-repo/semantics/articlereponame:CONCYTEC-Institucionalinstname:Consejo Nacional de Ciencia Tecnología e Innovacióninstacron:CONCYTEC#PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#20.500.12390/929oai:repositorio.concytec.gob.pe:20.500.12390/9292024-05-30 15:23:15.309http://purl.org/coar/access_right/c_14cbinfo:eu-repo/semantics/closedAccessmetadata only accesshttps://repositorio.concytec.gob.peRepositorio Institucional CONCYTECrepositorio@concytec.gob.pe#PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#<Publication xmlns="https://www.openaire.eu/cerif-profile/1.1/" id="f4c40e62-6cc2-4774-b4d8-c7fc7ace9923"> <Type xmlns="https://www.openaire.eu/cerif-profile/vocab/COAR_Publication_Types">http://purl.org/coar/resource_type/c_1843</Type> <Language>eng</Language> <Title>Comparative study of the removal of phenolic compounds by biological and non-biological adsorbents</Title> <PublishedIn> <Publication> </Publication> </PublishedIn> <PublicationDate>2009</PublicationDate> <DOI>https://doi.org/10.1016/j.jhazmat.2008.09.077</DOI> <SCP-Number>2-s2.0-62949125087</SCP-Number> <Authors> <Author> <DisplayName>Navarro A.E.</DisplayName> <Person id="rp01807" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Cuizano N.A.</DisplayName> <Person id="rp02421" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Lazo J.C.</DisplayName> <Person id="rp02456" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Sun-Kou M.R.</DisplayName> <Person id="rp01809" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Llanos B.P.</DisplayName> <Person id="rp01808" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> </Authors> <Editors> </Editors> <Publishers> <Publisher> <DisplayName>Elsevier</DisplayName> <OrgUnit /> </Publisher> </Publishers> <Keyword>pH</Keyword> <Keyword>Exchanged bentonite</Keyword> <Keyword>Cross-linked algae</Keyword> <Keyword>Partition coefficient</Keyword> <Keyword>Adsorption</Keyword> <Abstract>The ability of biological and non-biological adsorbents to remove 2-nitrophenol (2-NP) and 2-chlorophenol (2-CP) from aqueous solutions in batch experiments at room temperature was compared.
