Abstract— The impact of two strains of Pseudomonas bacteria and natural zeolite on the growth and elemental composition of barley plants was studied in an agrogray soil (Luvisol) artificially contaminated with cadmium in pot experiments. Application of P. fluorescens 21, or P. putida 23, or zeolite eliminated the heavy metal toxicity for …

zeolite mines producing an estimated 98,000 tons of natural zeolites, a 14% increase from 2018. Chabazite is mined in Arizona (Hyde, 1982; Flanagan, 2020) and clinoptilolite in New Mexico (Hyde, 1982). Although reported to have benefits as soil conditioners and growth media, these are less common than other uses. This bulletin gives a summary

The addition of zeolite increases water vapor adsorption on the soil. The studied zeolite has very large surface area, 125.5 m 2 g −1. The addition of zeolite to the soil results in an increase in surface area proportional (R2 = 0.99) to the zeolite fraction, x, in the soil–zeolite mixture: S = 128.9x + 52.1 m 2 g −1.

Zeolite. This study is based on evaluation of solidification methods for low-level radioactive liquid using natural zeolite. In classical method, LLW is decontaminated using zeolite and after the process spent zeolite becomes radioactive waste. After decontamination process, zeolite waste is solidified using cement, sand and water.

Firstly, natural zeolites were found in vugs in basalt rocks and in cavities. Afterwards, they were also discovered in sedimentary rocks (19th century). In 1756, Alex Fredrik Crönstedt, a Swedish mineralist, first identified natural zeolite as a mineral after he sampled crystals from a copper mine in Sweden.
