In　this　study,　carbon　nanotube　(CNT)　and　reduced　graphene　oxide　(rGO)　were　studied　for　their　potentials　as　novel　adsorbents　for　trace　concentrations　of　phosphorus　and　aluminum　in　water　and　wastewater.　Static　adsorption　results　demonstrated　that　CNT　and　rGO　employed　in　this　study　removed　up　to　65.6%　of　total　dissolved　Al　and　98.9%　of　P　from　a　natural　surface　water　and　a　secondary　wastewater　effluent.　Hydrogen-bonding　interactions　between　CNT/rGO　and　oxyanions　were　hypothesized　to　contribute　to　the　adsorption　process.　Accordingly,　acetaminophen　(AAP),　a　pharmaceutical　compound　known　to　form　hydrogen　bonding　with　CNT,　was　spiked　into　the　real　water　as　a　competitor　for　P　and　Al　adsorption.　Subsequent　sorption　results　showed　that　the　presence　of　AAP　reduced　Al　and　P　adsorption　by　CNT　and　rGO　by　9.3%-18.4%　and　11.2%-18.2%,　respectively.　These　results　suggest　that　hydrogen　bonding　interactions　with　CNT/rGO　influenced　the　adsorption　of　P　and　Al　species.　In　addition,　pH　effect　investigation　on　Al/P　removal　further　verified　the　above　opinion.　Overall,　this　study　provided　important　evidence　and　insights　into　CNT/rGO　adsorption　of　P　and　Al　species　from　water　and　wastewater,　which　expanded　our　understanding　on　the　ability　of　carbonaceous　nanomaterials　for　advanced　water　and　wastewater　treatment.　(c)　2019　Elsevier　B.V.　All　rights　reserved.
