Providing drinking water with safe arsenic levels in Latin American (LA) countries (a total of
22 countries) is a major current challenge. Arsenic's presence in water has been neglected …

The hazardous toxicity of dye materials, even in low concentrations, harms ecological
systems. It releases a large number of contaminants into the water, resulting as waste water …

Abstract Purpose of Review Heavy and toxic metals are becoming more prevalent in the
water sources of the globe, which has detrimental repercussions for both human health and …

The by-product of the traditional Fenton reaction, colloidal arsenic-‑iron oxide, is migratable
and may cause secondary environmental pollution. This paper reported a new strategy …

Photocatalytic oxidation of arsenite (As (III)) to arsenate (As (V)) was studied in aqueous
solution using a series of WO 3/TiO 2 semiconductors readily synthesized through sol-gel …

Aquacultures are a sector facing a huge development: farmers usually applying antibiotics to
treat and/or prevent diseases. Consequently, effluents from aquaculture represent a source …

In this paper, we discuss the importance of distinguishing the contributions of photolysis,
adsorption, sensitization, degradation and mineralization processes to the photocatalytic …

This study investigated the synthesis of α-Bi 2 O 3 needles by a co-precipitation method. The
isolated needles were annealed at temperatures ranging from 200 to 700° C and the …

In the present work, WS 2 nanoparticles and immobilized on chitosan and polycaprolactone
as biodegradable polymers as photocatalyst were developed and studied for photocatalytic …

Selenium contamination in water bodies is a concerning issue due to the harmful effects of
