“…When inorganic ammonium salt is used to modify the zeolite by impregnation, ammonium ions can enter the zeolite channel by exchange with cations in zeolite [16], but due to the influence of the cation site of the zeolite, they can only exchange with cations in the quaternary ring and hexagonal ring on the zeolite surface [17], and the nitrogen content introduced is low. When organic nitrogen-containing substances are used to impregnate zeolites, the nitrogen-containing functional groups are easily grafted onto the zeolite surface [18].…”

In this study, through simple ammonia impregnation, more amine functional groups could be introduced into the zeolite 4A synthesized using fly ash, which efficiently improved the mercury ion removal capacity of modified zeolites. The impregnation-modification mechanism of NH3·H2O, ammonium chloride, and silane coupling agent (KH792) for zeolite 4A, and the Hg2+ ion removal-efficiency by aminated zeolites, were studied and compared. Through ion exchange and hydroxyl reactions, NH3·H2O impregnation introduced the same kinds of nitrogen-containing groups into zeolite as KH792 grafting, which was more than the NH4Cl modification. The Hg2+ ion adsorption capacity of NH3·H2O-zeolite was higher than those of KH792-zeolite and NH4Cl-zeolite through ion exchange and the complexation of nitrogen-containing groups. When coexisting with Pb2+, Cu2+, and Zn2+ ions, the Hg2+ ion removal rate of NH3·H2O-zeolite was still higher than 99%. After five adsorption and desorption cycles, the Hg2+ ion removal rate of NH3·H2O-zeolite was 72.03%. When NH3·H2O-zeolite was added to the leaching of mercury-contaminated soil, the content of soluble mercury significantly decreased. Therefore, we synthesized a potential cheap and safe adsorbent using fly ash as the main raw material through the simple NH3·H2O impregnation modification for the treatment of mercury-contaminated water and soil.

“…The effectiveness of organo-zeolite fertilizer consisting of a mixture of grinded zeolite tuffs and coal waste has been studied in a number of works [30][31][32][33][34]. The decomposition of organic waste produces ammonium ions, which are adsorbed in zeolite tuffs [35].…”

Recently, for improving physical and chemical properties and restoring natural fertility the introduction of unconventional natural resources (so-called agronomic ores) has been widely used in many countries [4]. Nitrogen fertilizers have the leading role in increasing the yield of agricultural crops. This is caused by the extremely important role of nitrogen in plant's life. Used nitrogen fertilizers have a significant flaw: their efficiency coefficient does not exceed 30-40%, the rest is washed out into underground horizons. Potassium and nitrogen

“…Zeolite is natural occurring mineral known as a suite of porous, fine-grained minerals commonly found in certain near surface, sediment rocks, having special physical and chemical properties that could make them valuable for agricultural practices [10] [11]. Some of the characteristics of zeolites that potentially make them desirable for improving the properties of soils are a large internal porosity that results in water retention, a uniform particle-size distribution that allows them to be easily incorporated, and high cation-exchange capacity that retains nutrients [15].…”

“…Integrated zeolite inside Greenfeed® Slow Release Fertilizer has the ability to retain moisture is another positive aspect to be use as a soil amendment. Zeolites can hold up to 60% of their weight in water due to the high porosity of their crystalline structure [9] [10] [11]. Zeolite acts as a non-form changing, permanent water reservoir, which provides prolonged moisture during dry periods as well as promoting rapid re-wetting and improved lateral spread in the root zone during irrigation.…”

Fertilizer issues such as overuse, leaching and soil degradation are becoming severe in worldwide plantation areas. To secure current food production, prevention measures on these issues are relatively limited on agricultural production areas. Slow release fertilizer is prevailing over past years due to its significant effects on prevention of fertilizer leaching and less harm to soil and underground water. We presented here the mechanisms of a novel zeolite-based slow release fertilizer including its properties as reservoirs of nutrients, pH balancer and also water retainer in soil. By providing sufficient nutrients to soil, this fertilizer has commercially proven to give better growing environment to grower as well as labor saving and cost saving.
