In the crystal structure of the title salt, [Ag(NH(3))(2)](4)(C(7)H(6)O(7)S(2))(2)·H(2)O, the four independent Ag(I) complex cations all lie on special positions of m site symmetry, as do the two independent 2-hy-droxy-5-methyl-benzene-1,3-disulfonate anions. The Ag(I) cations exist in an almost linear coordination geometry [N-Ag-N = 175.2 (2), 178.08 (16), 175.8 (2) and 178.20 (19)°]. The wate...

1-(4-tert-butylphenyl)4-(4-trifluoromethylphenyl)carbonylthiosemicarbazide (OBS) and was synthesized by reaction of 4-tert-Butylbenzoic hydrazide with 4-(trifluoromethyl)phenylisothiocyanate. The influence many metal cations on the spectroscopic properties compound investigated in dmso-water (1:1) means emission spectrometry.The a series ions including Cu2+,Co2+ , Al3+,Cr3+,Fe3+, Pb2+, Ni2+, Cd...

The deposits of clinoptilolite (CLI) in Iran after activation with sodium chloride or sodium hydroxide solution was subjected to ion exchange with some heavy and toxic cations. The results showed that the absorption for Ca2+ (7.5 ppm), Cu2+ (50 ppm), Zn2+ (40 ppm), Cd2+ (40 ppm), Pb2+ (500 ppm) and Al3+ (5 ppm) were 95.2, 96.70, 93.30,99.12, 99.2 and 90.0 percents, respectively. The noteworth...

Colloidal CsPbX3 (X = Br, Cl, and I) perovskite nanocrystals (NCs) have emerged as promising phosphors and solar cell materials due to their remarkable optoelectronic properties. These properties can be tailored by not only controlling the size and shape of the NCs but also postsynthetic composition tuning through topotactic anion exchange. In contrast, property control by cation exchange is st...

A cloud-point extraction process using micelle of the cationic surfactant CTAB to extract Fe3+and Pb2+ from aqueous solutions was investigated. The method is based on the color reaction of Fe3+and Pb2+ with bromopyrogallol red at pH 5.0 and micelle-mediated extraction of the complex. The optimal extraction and reaction conditions (e.g., surfactant concentration, reagent concentration and effect...

In the title polymeric compound, [Pb(C(12)H(6)N(2)O(4))](n), the Pb(II) cation, located on a mirror plane, is N,N'-chelated by a 2-2'-bipyridine-5,5'-dicarboxyl-ate (bpdc) anion and is further coordinated by six O atoms from four carboxyl groups of bpdc anions in an irregular N(2)O(6) geometry. The carboxylate groups bridge the Pb(II) cations, forming a three-dimensional polymeric structure. Th...

The title compound, (C(12)H(16)N(2))(2)[PbBr(6)], is an organic-inorganic salt, with two doubly protonated N-(1-naphth-yl)ethyl-enediammonium cations and one octa-hedral hexa-bromidoplumbate(II) anion. The Pb(II) atom is located on a centre of inversion. The crystal structure consists of alternating inorganic and organic layers parallel to the bc plane. Face-to-face aromatic stacking inter-acti...

In this research, graphene oxide (GO) was functionalized by tannic acid to produce GO-TA and fabricate a novel functionalized graphene oxide/ polyacrylonitrile (PAN) nanofibrous as an adsorbent in order to remove two hazardous heavy metals from aqueous solutions. The results showed that the composite adsorbent can properly adsorb Pb2+ and Cd2+ metal cations, due to having the numerous potential...
