“…Biological templates have been investigated for the synthesis of porous inorganic materials, as they can derive morphologically controllable materials with structural specificity and unique functions [23][24][25][26][27]. In another study, we showed that the specific surface area of TiO2/SiO2 prepared by using diatoms as the biotemplate was significantly higher than the specific surface area of conventional TiO2/SiO2, which might be due to the formation of many accessible pores and channels [28].…”

TiO2 photocatalyst was prepared using cellulase as a biotemplate through a hydrothermal process. The as-prepared catalyst was characterized based on physicochemical techniques and was used to remove As(III) from contaminated water. The cellulase templated TiO2 photocatalyst (TiO2-cellulase) had a large specific surface area, which reached 166.6 m2·g–1. It also had a strong oxidation ability and, thus, behaved well in both photocatalytic oxidation of As(III) and dark adsorption. The pH of the solution had a negligible effect on the removal rate. TiO2-cellulase had a higher photocatalytic removal rate of As(III) than commercial Degussa P25 TiO2.

Arsenic (As) poses a threat to human health. In 2014, more than 200 million people faced arsenic exposure through drinking water, as estimated by the World Health Organization. Additionally, it is estimated that drinking water with proper microbiological quality is unavailable for more than 1 billion people. The present work analyzed a solar heterogeneous photocatalytic (HP) process for arsenite (AsIII) oxidation and coliform disinfection from a real groundwater matrix employing two reactors, a flat plate reactor (FPR) and a compound parabolic collector (CPC), with and without added hydrogen peroxide (H2O2). The pseudo first-order reaction model fitted well to the As oxidation data. The treatments FPR–HP + H2O2 and CPC–HP + H2O2 yielded the best oxidation rates, which were over 90%. These treatments also exhibited the highest reaction rate constants, 6.7 × 10−3 min−1 and 6.8 × 10−3 min−1, respectively. The arsenic removal rates via chemical precipitation reached 98.6% and 98.7% for these treatments. Additionally, no coliforms were detected at the end of the process. The collector area per order (ACO) for HP treatments was on average 75% more efficient than photooxidation (PO) treatments. The effects of the process independent variables, H2O2 addition, and light irradiation were statistically significant for the AsIII oxidation reaction rate (p < 0.05).

In India, where millions of people use groundwater for drinking, arsenic pollution in groundwater is a major environmental and public health issue. The review begins by analyzing the sources and causes of groundwater arsenic pollution, including natural geological processes and anthropogenic activities like mining and industrial discharge. It emphasizes India's most arsenic‐contaminated regions and the health risks of long‐term exposure. The review's second section focuses on the use of biosensors to find arsenic in groundwater. A potential method is provided by biosensors because of their great sensitivity, selectivity, and quick response. The benefits and drawbacks of several types of biosensors, including optical, electrochemical, and microbiological biosensors, are discussed. The utilization of nanomaterials, biomolecular recognition components, and miniature devices are only a few of the most recent developments in biosensor technology for arsenic detection that are studied. The review's last section discusses methods for bio‐remediating aqueous systems that have been contaminated with arsenic. Various bioremediation techniques are covered in detail, including microbial degradation, phytoremediation, and biosorption. The promise for removing arsenic using native microbes and plant species is highlighted, along with the difficulties of widespread application and long‐term sustainability. Overall, focusing on the detection of arsenic using biosensors and investigating bioremediation techniques, this review offers a thorough grasp of the arsenic poisoning in groundwater in India. In order to combat arsenic contamination and protect the health and wellbeing of the impacted populations in India, it emphasizes the need for interdisciplinary research and collaboration among scientists, engineers, policymakers, and local communities.
