A comprehensive review on BPA degradation by heterogeneous Fenton-like processes.

Synthetic organic pollutants emanating continuously in the ecosystem have become a global concern because of their toxicity and persistent nature. Bisphenol A (BPA) is one such pollutant which threatens public health and safety. It is a monomer used in manufacturing plastics, polycarbonate resins, epoxy resins and is a well-recognised endocrine disruptor mimicking estrogen.

A Review of the Latest Advances in Nanoparticle-Mediated Processes for Hexavalent Chromium Remediation from Water Bodies.

Hexavalent chromium (Cr(VI)) is a well-known carcinogen, and hence its removal from aqueous media is an important area of research in the field of environmental engineering. Adsorptive removal and catalytic reduction are the two most common techniques applied for this purpose. In this regard, nanoparticle-mediated technology has contributed significantly.

Supported metal and metal oxide particles with proximity effect for catalysis.

External influence is essential for any change to occur in this world. Similarly, the reaction path of a chemical reaction can be changed with the addition of a catalyst from outside. Sometimes a catalyst performs better when it remains associated with an inert substance, which is called a support material (SM).

Spectrophotometric determination of cationic surfactants in aqueous media using chrome azurol S as colour forming agent and 1-butanol as extracting solvent.

A simple spectrophotometric method for the determination of cationic surfactants (CS) is developed using an anionic dye, chrome azurol S (CAS) as an ion-association complex forming agent, and 1-butanol as an extracting solvent. In the aqueous solution CS such as cetyltrimethylammonium bromide (CTAB), cetylpyridinium chloride (CPC) and dodecyltrimethylammonium bromide (DTAB) reacts with CAS to form an ion-association complex which is extracted into 1-butanol to form a pink-violet coloured organic phase. The final concentration of CAS in surfactant solution is 165 μM.
