Investigation of Copper Sorption by Sugar Beet Processing Lime Waste (original) (raw)

In this preliminary study, the potential of lime waste generated from sugar beet processing to sorb copper (Cu) from dairy effluent was investigated. The research focused on the effects of varying pH levels and Cu concentration on the sorption capacity of lime waste. Results indicated that Cu sorption increased at lower pH levels, with the maximum sorption capacity observed at pH 6. X-ray absorption spectroscopy revealed the formation of Cu(OH)2, suggesting effective Cu immobilization. The findings imply that utilizing lime waste could mitigate Cu accumulation in soils irrigated with dairy effluent.
