Fracturing under ultrahigh vacuum (UHV, p ≤ 10-9 Torr) produces membrane fracture faces devoid of contamination. Such clean surfaces are a prerequisite foe studies of interactions between condensing molecules is possible and surface forces are unequally distributed, the condensate will accumulate at places with high binding forces; crystallites will arise which may be useful a probes for surface sites with specific physico-chemical properties. Specific “decoration” with crystallites can be achieved nby exposing membrane fracture faces to water vopour. A device was developed which enables the production of pure water vapour and the controlled variation of its partial pressure in an UHV freeze-fracture apparatus (Fig.1a). Under vaccum (≤ 10-3 Torr), small container filled with copper-sulfate-pentahydrate is heated with a heating coil, with the temperature controlled by means of a thermocouple. The water of hydration thereby released enters a storage vessel.

Lim bah industri klor alkali termasuk limbah 83 dari sumber yang spesifik. Pembakaran lirnbah padat industri kimia terpadu, yang memproduksi kaustik soda, VCM dan PVC akan menghasilkan abu. Limbah cair media proses polimerisasi PVC setelah pengendapan disebut spent pure water (SPW). Abu sisa pernbakaran, Solid Waste /ncenerator (SWI) ini dapat dimanfaatkan sebagai adsorben  untuk SPW. Sesuai dengan model Freundlich isoterm, SW! mempunyai daya adsorpsi terhadap biru metilen lebih baik dari pada karbon aktif, dan mampu menurunkan turbiditas SPW sampai sekitar 95%.
