“…These changes ultimately control the interaction of adsorbate with the adsorbent surface. In our case, the pH of the solutions studied (pH between 6.5 and 7), in the presence of MCM-41-NH2, causes deprotonation of the pharmaceutical residues used, which results in a strong interaction with the surface of the material [12,23,27]. The study of the linearization of the Langmuir, Freundlich and Sips (Langmuir-Freundlich) models, defined above, gives the different parameters of the three models which we have gathered in Table 3.…”

“…Mesoporous silica has been used in many practical applications such as catalysis, drug transfer and adsorption, and therefore, it has been considered as one of the effective adsorbents for the removal of various organic and inorganic pollutants, specially the pharmaceutical residues [19][20][21][22]. The main adsorption properties of mesoporous silica are high surface area, high porosity, wellstructured properties, the possibility of surface modification and functionalization, and regular channel structure, such as SBA-n (SBA-3, SBA-15, SBA-16), HMS, MSU-x and M41S (MCM-41) materials [23][24][25][26].…”

This study aims to evaluate the adsorption performance of an amine-functionalized MCM–41 mesoporous silica nanoparticles system (MCM–41–NH2) as an adsorbent for the removal of different pharmaceutical pollutants from aqueous solutions. The modification of MCM-41 was achieved through post-synthesis treatment in the presence du 3-Aminopropyltriethoxysilane (APTES). Surface and structural characteristics of MCM-41 and MCM–41–NH2 were examined using N2 adsorption–desorption analysis, X-ray diffraction, Fourier transform infrared spectroscopy, and point of zero charge analysis. In addition, thermal stability was investigated by thermogravimetric analysis. The kinetics study shows that adsorption on MCM–41–NH2 follows pseudo-second-order rate expression. Isotherm study showed that the experimental data fitted well with the Langmuir equation. Moreover, the maximum adsorption capacities of MCM–41–NH2 were: (129.8, 272.0, 233.2 and 318.6) mg/g for Diclofenac, Ibuprofen, Oxacillin and Trihydrated Amoxicillin respectively). The adsorption is controlled by the surface charges of the adsorbent and the adsorbate. Compared with other adsorbents, MCM–41–NH2 was more effective for the different pharmaceutical removal.

“…Rapid industrialization, urbanization, steep demand of water and lack of exposure to people result in industrial effluents, sewage waste, and loss in forest cover, sprawling towards Ganga flood plains and unmanaged disposal of waste. These factors directly and indirectly ground environmental toxicity and have severe impact on Ganga River, which deteriorates river water quality and further imperil aquatic biota [10][11]. Major pollutants found in industrial waste and sewage are heavy metals, volatile organic compounds (VOCs), pesticides, fertilizers, plastics related waste, microbial pathogens and parasites [12][13][14].…”

Ganga River is the lifeline for socio-economic development of India. The unlimited desire of human and anthropogenic activities degraded the water quality of Ganga River, especially in Haridwar. The present study investigated the significant impact of lockdown on physio-chemical status of the Ganga River in Haridwar. Study also revels the significant augmentation of heavy metals as lockdown released, however, average daily dose and hazard index has advocacy in suitability of Ganga River water in Haridwar for their utility. Moreover, this is the first study that highlights Cancer Risk value of Arsenic (As) and Chromium (Cr) in Ganga River water in Haridwar exceeded over the target risk of 1 × 10 −4 . The values for As was calculated as 0.000172 -adult and 0.00074 -children, whereas, for Cr was estimated as 0.000067 -adult and 0.00029 -children. This indicates the ingestion of Ganga River water (except for Cr values for adult which is less than targeted value) in Haridwar for long time may increase the probability of cancer to the population. Therefore, it is imperative to formulate such policies and strategies that keep ritual values and maintain water quality.
