Boron is biologically an essential nutrient for many plants but high boron concentrations in irrigation water cause toxic effects whereas low abundances require boron addition to maximize crop yields. High boron levels in drinking water can be also toxic to humans. There is no easy method for the re

In this study removal of boron from aqueous solutions by adsorption was investigated and experimental design was applied. Cerium oxide was used as adsorbent. In the first part of study 3 parameters effect performance and two levels of these parameters were investigated. Parameters that were chosen t

In this study, the removal of nitrite from aqueous solution by adsorption was investigated. Sepiolite and powdered activated carbon (PAC) were used as adsorbents. In order to investigate the adsorption mechanisms, three simplified kinetic models, i.e., pseudo-first-order, pseudo-second-order and int

Organized industrial estates (OIEs) have been supposed to an alternative to industrial pollution control, in particular, in developing countries. However, a wastewater management strategy should be well established in the planning phase of them to save investment and operational costs of the central

Compact and uniform MFI layers were synthesized on seed coated supports. Seeding improved the membrane performance and yielded good quality MFI membranes. n-/i-C4H10 selectivity

The trend observed in desorption data is not similar to the trends of water and ethylacetate fluxes obtained from pervaporation experiments in our previous work [11]. This is caused by that while only sorption phenomena is effective in desorption study, diffusion is also effective in pervaporation.

CH4 N2 0.4 Fig. 2. Single gas permeances for tubular MFI membranes (composition: 80SiO2:16TPAOH:1536H2O; T = 95°C; t = 72 h).

MFI membranes with high permeances, separation selectivities between 4 and 8.5 and ideal selectivities between 10 and 70 were synthesized in a flow system with circulation. Such high permeances and similar selectivities are seen in membranes synthesized at low temperatures. Carried out at low temper
