Studies on removal of hydrophobic organics from contaminated soil by washing process
PublicationZbadano efektywność wymywania NAPL ze złoża piaskowego za pomocą roztworów dwóch niejonowych surfaktantów: polioksyetylenowanego alkoholu tłuszczowego (Rokanol NL6) oraz alkiloglukozydu (Triton BG10). Jako NAPL zastosowano dwa węglowodory - dodekan i heksadekan. Oba surfaktanty były relatywnie efektywne w usuwaniu dodekanu. Ze wzrostem stężenia surfaktantu obserwowano wzrost efektywności wymywania dodekanu, jednakże Rokanol NL6...

Flue gas treatment for SO2 removal with air-sparged hydrocyclone technology
PublicationOpisano wstępne wyniki badań laboratoryjnych usuwania SO2 z mieszaniny gazów z zastosowaniem reaktora cyklonowego (ASH). Do absorpcji stosowano wodę wodociągową oraz roztwór alkaliów. Zbadano wpływ natężenia przepływu gazu, natężenia przepływu wody oraz długość elementów ASH. Stwierdzono, że efektywność absorpcji SO2 z powietrza stosując technologię ASH jest porównywalna z efektywnością metod konwencjonalnych.

Flue gas treatment for SO2 removal with air-sparged hydrocyclone technology
PublicationWyniki badań dowodzą, że reaktor cyklonowy jest wysokosprawnym absorberem. Absorber cyklonowy pozwala na osiągnięcie stopnia redukcji 97% dla samej wody i zawartości dwutlenku siarki w fazie gazowej 5 mg/dm3. Dwutlenek siarki był usuwany również w wodnym rozworze alkaicznym (0.01 mol NaOH/dm3).

Removal and retention of selected heavy metals in components of a hybrid wetland system
PublicationProwadzone badania z określeniem możliwosci retencjonowania metali ciężkichw systemie hybrydowej oczyszczalni hydrofitowej. Wykazano, że znaczna rete- ncja tych pierwiastków następowała w wyniku sorpcji. Przeprowadzona ekstra- kcyjna analiza sekwencyjna wykazała, że Pb2+ i Cu2+ zostały zakumulowane w połączeniach trwałych i nie powinny ulegać wymywaniu z oczyszczalni. Nato- miast Cd2+ wskutek sorpcji we frakcjach labilnych może...

Crystal Growth, Structure, and Magnetism of the 2D Spin 1/2 Triangular Lattice Material Rb3Yb(PO4)2
PublicationThe single-crystal growth, crystal structure, heat capacity, and anisotropic magnetization characterization of Rb3Yb- (PO4)2, a Yb-based triangular lattice material, are presented. Single-crystal X-ray diffraction shows that Rb3Yb(PO4)2 exhibits [Yb(PO4)]∞ layers, with the Yb in an ordered plane of equilateral triangles. One phosphate group oxygen that is not a near neighbor of the magnetic Yb displays positional disorder. The...

Modelling of shear zones during quasi-static granular silo flow using material point method (MPM)
PublicationThe paper focuses on confined silo flow of cohesionless sand. The problem considered is a quasi-static flow in a plane strain model silo with parallel walls simulated with the material point method (MPM). The simulation used a non-local hypoplastic constitutive model. Initially, the paper validated the implemented numerical approach with basic element tests and a plane strain compression test. The subsequent MPM calculations for...

Generation of random fields to reflect material and geometric imperfections of plates and shells
PublicationThe paper covers two patterns of random field generation: conditional acceptance – rejection method and Karhunen – Loève expansion. The generation of two-dimensional random fields is essential in plates and shells analysis, allowing for a relevant limit and critical state assessment of geometrically and ma-terially imperfect structures. The features of both generation methods dedicate them to selected problems.
