“…A series of SA/Lan hydrogel spheres were prepared by sodium alginate cross-linking with lanthanum chloride solution using La 3+ concentration of 0.1 to 10 wt.%. 2 g•L −1 SA/ Lan hydrogel spheres were added to 30 mg•L −1 of CR solution shaking for 4 h. As shown in Figure 4, the doping of La ions is useful for the removal of CR [25]. Te adsorption of CR is very low when not doped with La.…”

Sodium alginate-lanthanum (SA/Lan) hydrogel spheres were prepared by ion cross-linking method to remove Congo Red (CR) in an aqueous solution. The adsorption performance was assessed through batch experiments. The experiment revealed that the highest adsorption capacity of SA/Lan for CR was achieved when the mass concentration of La3+ was 1%, the dosage was 2 g·L−1, the initial concentration of CR was 30 mg·L−1, the adsorption time was 60 min, and the reaction temperature was 25°C. The adsorption capacity of 10.81 mg·g−1 was the corresponding figure. The adsorption process was consistent with the Langmuir and pseudosecond-order models.

“…A incorporação de óxidos metálicos na composição de materiais compósitos é uma estratégia para a obtenção de adsorventes com propriedades aprimoradas (Souza et al, 2019). Os óxidos de níquel são adsorventes escolhidos devido à alta estabilidade química e térmica, compatibilidade ambiental e baixo custo (Zheng et al, 2017).…”

Neste trabalho o adsorvente compósito Ni2O3/NaZSM-5 foi obtido via mecanossíntese, caracterizado por técnicas como DRX, pHPCZ, MEV e adsorção de N2 a 77 K e avaliação do seu potencial como adsorvente de corante vermelho Congo. A incorporação de Ni2O3 na zeólita NaZSM-5 aumentou a sua eficiência de adsorção em comparação com a NaZSM-5. Estudos cinéticos mostraram que o modelo de pseudo segunda ordem (PSO) apresentou o melhor ajuste com os dados experimentais.
