Języki publikacji
Abstrakty
As part of the work, experiments were carried out on a laboratory scale to assess the effectiveness of the use of composite capsules based on halloysite and sodium alginate for the adsorption of copper from rainwater. The halloysite was subjected to acid activation prior to the encapsulation process. The characteristics of the capsules obtained were determined by means of SEM surface imaging, nitrogen adsorption by the BET method and pHPZC measurement by the suspension method. Adsorption was studied using various operational parameters such as adsorbent dose, contact time, pH and concentration of copper ions in the rainwater. A high percentage of copper ions removal was demonstrated, i.e. 72% for halloysite (H), and 83% for activated halloysite (HA) for a dose of 2.0 g/L. Adsorption of Cu (II) was consistent with pseudo-second order kinetics. The adsorbents showed a high adsorption capacity at the level of 11.03 mg/g, determined by the Langmuir isotherm model. This model fit well with the experimental data.
W ramach pracy przeprowadzono eksperymenty w skali laboratoryjnej mające na celu ocenę efektywności wykorzystania kapsuł kompozytowych na bazie haloizytu i alginianu sodu do adsorpcji miedzi z wód opadowych. Haloizyt został poddany aktywacji kwasem przed procesem enkapsulacji. Charakterystykę otrzymanych kapsułek określono za pomocą obrazowania powierzchni SEM, adsorpcji azotu metodą BET oraz pomiaru pHPZC. Adsorpcję badano za pomocą różnych parametrów operacyjnych, takich jak dawka adsorbentu, czas kontaktu, pH i stężenie jonów miedzi w wodzie deszczowej. Wykazano wysoki procent usuwania jonów miedzi, tj. 72% dla haloizytu (H) i 83% dla haloizytu aktywowanego (HA) dla dawki 2,0 g/L. Adsorpcja Cu (II) była zgodna z kinetyką pseudo drugiego rzędu. Adsorbenty wykazywały wysoką zdolność adsorpcji na poziomie 11,03 mg/g, wyznaczoną za pomocą modelu izoterm Langmuira. Model ten dobrze pasował do danych eksperymentalnych. Stwierdzono, że kapsułki kompozytowe haloizytu i aktywowanego haloizytu mogą być stosowane jako wydajny i tani adsorbent do usuwania miedzi z wody.
