For environmental applications, the production of inexpensive but superior adsorbents is essential. The Taguchi method was applied as an experimental design in this paper to determine optimum conditions for removal crystal violet dye using pistachio shell powder batch experiments. effects pH (3–9), initial concentration (2–10 mg•L-1), contact time (30–360 mins) and adsorbent dose (0.25–4 g•L-1)...

Prominent progress has been made in nitride semiconductor since high bright blue LED has developed in 1993. It has also expanded to an industry after applied to white LED. These LEDs are produced by the epitaxial growth of nitride semiconductor layers on sapphire (a Al2O3) substrate. On the other hand, recording density in optical disks has increased from CD in 1980s to DVD in latter 1990s. Las...

Thin-film composite (TFC) membranes show great potential in dye nanofiltration but their performance still required further improvement. In this work, ultra-small EMT zeolite nanocrystals were embedded into the interfacial polymerized polyamide (PA) layer supported on porous nylon via spray dispersion method and used separation. Ultra-small nanosized crystals with plate-like morphology synthesi...

Activated carbon (ACBS) derived from Balanites aegyptiaca seed shell was employed to remove crystal violet (CV) aqueous medium. The characterization of this ACBS has been conducted using analytical techniques such as SEM and EDS. adsorption parameters investigated were: contact time (5-120 min), temperature (303-333 K) initial concentration (100-500 mg/l). data were interpreted by kinetic, isot...
