The development of photocatalysts for efficient photodegradation of emerging water pollutants is a subjectof global concern in recent years. In this study, the photophysical properties of TiO2 were modified bydoping with different concentrations of boron (B-TiO2) and nitrogen (N-TiO2) by following a sol–gel routeof synthesis. The type and concentration of dopants were optimized to achieve maximum degradation ofacetaminophen (ACT) and monocrotophos (MCP) in aqueous solutions. UV DRS analysis shows that thebandgap of TiO2 (3.2 eV) reduced up to 2.96 and 2.27 eV in B-TiO2 and N-TiO2 samples, respectively. The presence of dopants inside the crystal lattice of doped TiO2 was confirmed with X-ray diffraction(XRD), Micro Raman, Fourier Transform infrared spectroscopy (FTIR), and X-ray photoelectron spectroscopy(XPS). The XRD data confirmed that the presence of these dopants promotes the rutile phasetransformation in TiO2 to various extents. The doping of B decreased the surface area and pore volumeof TiO2, whereas N doping had increased these properties. The XPS spectra showed the formation ofTi-O-B and Ti-O-N type linkage, indicating the presence of interstitial B and substitutional N atoms inTiO2 crystal lattice. The B doped samples exhibit more enhancement in photodegradation efficiency ascompared to N doped samples. Under optimized conditions, 5% B-TiO2 showed 95% and 71% degradationof ACT and MCP, respectively. The degradation pathway for both ACT and MCP involving their intermediateswas discussed through Mass spectrometry analysis. The cost-effectiveness of the most efficientdoped catalysts and commercial catalysts were compared with the ACER tool and turnover frequency.

Recent studies have identified sprue-like illness associated with the use of the antihypertensive agent olmesartan medoxomil. However, whether this condition is specific to the use of olmesartan or is associated with the use of drugs belonging to the class of “sartans” remains to be clarified. A 45-year-old woman with chronic kidney disease along with hypothyroidism and hypertension presented with chronic diarrhea and significant weight loss. Endoscopy of the upper gastrointestinal tract showed scalloping and grooving of the duodenum, and histopathological examination showed subtotal villous atrophy. She was on telmisartan for hypertension, which was discontinued. Subsequently, diarrhea ameliorated dramatically, and she regained weight. To our knowledge, this is the first study to report telmisartan-associated sprue-like enteropathy. Further, we have reviewed the cases of patients with sprue-like enteropathy caused by valsartan, irbesartan, and eprosartan. (Intest Res 2017;15:419-421)
