Introduction: Detergents lead to many environmental problems. The main aim of this study was to evaluate sequencing batch reactor (SBR) efficiency on Linear alkyl benzene sulfonate (LAS) removal. Materials and Methods: In this experimental study, to investigate the removal efficiency of LAS, a SBR reactor was used. A roughly 12-hour operating cycle was chosen which included the discharge time ...

Surfactants are one of the major components (10- 18%) of detergents and household cleaning products and are used in high volumes in developed countries. In the present research work, the ability of rice husk as a low cost adsorbent for anionic and nonionic surfactants in wastewater has been studied. The maximum removal efficiency for anionic surfactants was 97%, in an aqueous solu...

In the centrosymmetric title compound, C(18)H(28)Br(2)O(2), the alkyl chains adopt a fully extended all-trans conformation and each of them is almost planar. In addition, the alkyl chains are coplanar with the benzene ring. Inter-molecular Br⋯Br inter-actions [3.410 (3) Å] are present, resulting in a one-dimensional supra-molecular architecture.

The asymmetric unit of the title compound, C18H30O2, contains one half-mol-ecule situated on an inversion center. The alkyl chain adopts a fully extended all-trans conformation. The C atoms of the alkyl chain are almost coplanar, with a maximum deviation of 0.042 (6) Å from the mean plane,which is inclined to the central benzene ring by 6.80 (9)°. The crystal packing exhibits no short inter-mol...

Heavy alkylated benzene (HAB), which is a by-product in linear alkylbenzene (LAB) production by UOP process, is separated by distillation from LAB and consists of a range of components such as polyalkylbenzenes, diphenylalkanes, alkyl tetralins, and alkylindans. The products of sulfonation of HAB or its distillation cuts are of wide industrial applications such as emulsifiers, dispersants in lu...
