Polymerization of β‐cyclodextrin in the presence of bentonite clay to produce polymer nanocomposites for removal of heavy metals from drinking water

“…These oxygen atoms are highly friendly to positive charged molecules owing to strong electrostatic interactions. Various studies on the β‐CD molecules have confirmed the strong interaction between oxygen atoms and cations groups . We have also reported the intense interaction between β‐CD and Cu 2+ .…”

Structure and Vitamin D₃-Binding Affinity of Milk Proteins

“…This suggested that there may be another interaction involved. Literature data on HPβCD and VD 3 interaction indicates that a 2:1 binding may occur 104 . That is to say at high concentrations, two molecules of HPβCD bind to one molecule of VD 3 .…”

O uso de corantes alimentícios como tema gerador em aulas experimentais de Química

“…Os valores apresentados são os valores médios ( ̅ ) obtidos a partir da equação ̅ = A espectroscopia de UV-Vis limita-se a moléculas que apresentam sistemas conjugados [47], mas que pode ser aplicado a várias situações problema, desde o monitoramento de parâmetros ambientais [49], questões relacionadas à saúde [50,51] ou na alteração e estudo de novos materiais [52,53]. As moléculas que apresentam sistemas conjugados ou insaturados estão presentes em sistemas químicos, físicos e/ou biológicos em amostras sólidas, líquidas ou gasosas [54][55][56][57][58][59]. Os espectros de ultravioleta correlacionam a intensidade de absorção com o comprimento de onda máximo da amostra.…”
