“…Humic acid will adsorb more heavily on Pb heavy metal ions with longer contact times. However, during specific contact durations, the Pb heavy metal ions can be absorbed ideally and there may also be a reduction in adsorption [19].…”

This research focuses on the batch adsorption process, then looks for kinetic models and Freundlich model adsorption isotherms. In the process of adsorbing the heavy metal Pb, humic acid from goat dung has the potential to be employed as a promising adsorbent since it offers benefits, including being economical, being able to work accurately, quickly, sensitively, selectively, and helping to maintain public health. Parameters for testing humic acid from goat dung as an adsorbent for heavy metal Pb were determined by optimizing pH test variations, contact time, and concentration of Pb solution. Humic acid from goat manure could work optimally to absorb heavy metal Pb at pH 5, contact time 30 minutes, and metal concentration Pb 20 ppm with an adsorption capacity of 19.784 mg/g. Data modeling revealed that the adsorption process followed a pseudo-second-order kinetics model with the acquisition value of R² = 0.9595 and the Freundlich isotherm with the acquisition value of R² = 0.9166.

Liyangan buries some artifacts in volcanic sediment, including pollens. Reconstructing ancient plant diversity requires good quality in an adequate amount of genomic DNA from fossilized pollen. The current study was aimed to separate pollens from their sediment and extract the pollens. The separation was done according to different protocols (BALAR’s and Geology’s), DNAs were extracted by applying modified-CTAB and mini Genomic DNA Mini Kit. Current data showed the two separation and extraction protocols were able to separate fossilized pollens and so to extract them. The BALAR method combined with CTAB resulted in 314µg/ml to 887µg/ml while a lower amount of 382µg/ml to 852µg/ml were obtained when extracted by DNA Mini Kit. The Geology protocol combined with CTAB resulted in even lower concentrations (43µg/ml to 230µg/ml); and 22 µg/ml to 216 µg/ml by DNA Mini Kit. The BALAR’s protocol performed a better result in separating fossilized pollens from other materials. Both extraction methods resulted in an adequate amount of genomic DNA, although in quite low quality.
