| Tartalmi kivonat: | Plastics has become became a major consumable product and alternative in agriculture as a result of its playing role in energy conservation, maintaining of uniform soil temperature, and controls of weeds and fertilizer transport and thereby contaminate the soils. This research aims to provide the cost-effective method for microplastics separation and extraction from the agricultural soils. The soils were randomly collected from the greenhouse farming and conventional agriculture. The plastics used for recovery tests were collected from the field and cut off into pieces. Result from the field shows that density separation with ZnCl2 using this method has the highest extraction capacity (400 ±100 pieces/Kg) and recovery rate (90%) compare to other floatation solutions. The method was very effective in extracting both low and high densities microplastics. Furthermore, the results infer that NaCl2 and distilled H2O were effective in extracting low densities microplastics such as LDPE and PP. This method provides several alternatives depend on the economy and target of users. |
